C000885 The Athanasii Kircheri triangle filled with non-negative integers. The original triangle used by Athanasii Kircheri in Mundus Subterraneus can be found on page 24. In the OEIS it is the sequence 071797. Now, when we fill this triangle with non-negative integers, we get the following figure: The symmetry line of this triangle The central column of this triangle is the sequence 002378 oblong numbers = 2 * 000217 the triangular numbers. Notice that, in terms of values, the line of symmetry is to the right of the central column: 1+2=3 4+5+6=7+8 9+10+11+12=13+14+15 ...and so on. We have prime numbers on both sides of the central column. All rows start on the left with a 000290 square number, go through an 002378 oblong number and end with a number 005563 (square minus 1). Then, we have: $$square  2022-09-28, 12:04 #2 Charles Kusniec Aug 2020 Guarujá - Brasil 107 Posts C000886 The Athanasii Kircheri triangle filled with positive integers C000886 The Athanasii Kircheri triangle filled with positive integers. When we fill the Athanasii Kircheri triangle with the positive integers, we get the following figure: This triangle is also known as Klauber's triangle. He called this triangle the "triangle of primes". In the OEIS this triangle is mentioned in sequence 000027 in Kival Ngaokrajang's study. The row sum is 005898 \(\pm 2y^{3}-3y^{2} \pm 3y-1 = (2y-1)(y^2-y+1) =$$central column * row length = (oblong+1) * odd = central polygonal numbers * odd $$= (2y^3-3y^2+y)+(2y-1) =$$ the product of two consecutive numbers multiplied by the sum of the two consecutive numbers plus the odds $$= y^3+(y-1)^3 =$$ the sum of two consecutive cubes. The partial sum of 005898 is 037270 = $$\frac{\left( y^{2} \right) ^{2} + y^{2}}{2}$$ 1st partial difference of 005898 is 005897 = 2 * 056107. 2nd partial difference of 005898 is 017593 = 2 * 016945 = 6 * 005408. 3rd partial difference of 005898 is 010851 = 6 * 007395.

The number of elements in a row is equal to the row number. Continuing with only one element at the top, the next possible triangle has 1 element in the first row, 3 elements in the second row, 5 elements in the third row, 7 elements in the fourth row, and so on. The number of elements in a row is an odd number equal to $$(2*row \ number-1)$$. By sequentially numbering each cell in each row, we get the following triangle: This last triangle has the shape shown in Kircheri, P. Athanasii. (1664) Mundus Subterraneus, pg. 24. We will call this triangle shape the Kircheri triangle. In OEIS, this triangle is the sequence 071797. The sum of its y-th row is equal to $$2y^2 \pm y$$, which yields the n-th hexagonal number, 000384 The square numbers plus oblong numbers. The partial sum of the square numbers plus oblong numbers is 002412 the hexagonal pyramidal numbers, or greengrocer's numbers. The partial differences of the square numbers plus oblong numbers is $$\pm 4y+1$$ 016813. The partial differences of $$\pm 4y+1$$ is 010709 constant sequence: the all 4's sequence.

 2022-09-29, 00:29 #4 Charles Kusniec     Aug 2020 Guarujá - Brasil 11010112 Posts Kircheri triangle filled with non-negative integers and the OEIS sequence A055112 C000885 The Athanasii Kircheri triangle filled with non-negative integers is the example in the sequence 055112. In this triangle, the central column is 002378 (oblong numbers) or 2 * 000217 (triangular numbers). - Bruce J. Nicholson, Aug 31 2017 The first vertical column to the left of the central column is 165900, Values of Fibonacci polynomial n^2±n–1. Also, 165900 = n(n–1)±(n+(n–1)) = oblong ± odd = 002378 ± 005408 is the sum or difference of the product of two consecutive integers and the sum of those two consecutive integers. Almost similar, the sequence 055112 = n(n-1)*(n+(n-1)) = central column * row length = oblong * odd = 002378 * 005408 is the product of two consecutive integers multiplied by the sum of those two consecutive integers. The sequence of square numbers 000290 forms the left edge of the triangle. The prime numbers of the sequence 307508 are located between the left edge 000290 and the central column 002378. The sequence of (square minus 1) numbers 005563 forms the right edge of the triangle. The prime numbers of the sequence 334163 are located between the central column 002378 and the right edge 005563.

Some of us spend more time than we should drilling down on ideas. Even ideas that turn out to be less than optimal. Often thrown up as a distraction by those who don't actually want us to get our jobs done.

You have thrown out thousands of words (and even more numbers) without really explaining your argument. Heuristics suggests this means you aren't serious.

Care to change our preception?

Believe it or not, we are all ears for serious (a waste of time otherwise)...

Dear Chris Halsall,

I humbly ask for all possible forgiveness for giving the impression that I am not "serious and wasting your time".

That was never my intention and if that is happening, I would certainly like to change your precept.

1. I do not participate in any other forum.

2. Everything I write I do alone, without help or revision, much less exchange of ideas.

3. I am finding it very difficult to quickly show the big picture as I have several studies in several directions that tie together. Writing everything out takes time and my productivity is low.

4. For example this last post you used to consider your fatigue of my words and numbers is directly related to the new class of numbers I wrote at https://www.mersenneforum.org/showthread.php?t=27328. At the same time, everything I wrote in "How and why Legendre's conjecture works" I have other studies extending that to prove Goldbach's conjecture and Landau's problem at the same time.

5. Many things and solutions that I write are those that I cannot find in the literature available on the Internet. Many things are new and many I don't know if they are new. One example was my post on "Divisibility by 7". Since I couldn't find the sequences in OEIS, I thought it was something new. Maybe that is why you might have a bad impression of my posts.

6. On the other hand, writing all this takes time. Once, to figure out a table, I had to generate a dozen other tables, each with over 20 columns.
... but I never posted anything that didn't make mathematical sense.

CONCLUSION: If this were a soccer game, I would say that I am just a player. The field, the ball, the judges, the fans are all yours. The decision is yours.

Please, let me know if you prefer me to continue or stop sending the ideas and studies here.

Thank you.

Charles... That was a well thought out answer to my questions. To share, I hated sports as a child...

I now know you are not a 'bot. Sorry, we actually have to manage that kind of "attack surface" around these here parts. I'm only half joking... 9-)

Not all "get" the humor. But those that do tend to also get the deeper stuff.
