what should I post ?
most of what I can think of I probably already have posted somewhere like the trivial results that
edit: yep so trivial I messed up it's statement. basically I was just using the fact that: 1(2x+1)^2 = 4x^2+4x+1 = x(4x+3)+(x+1) 2(2x+1)^2 = 8x^2+8x+2 = x(8x+7)+(x+2) which technically is: because m=0 for the 1 case. so this is just a specific case of a more general algebraic fact.

closest thing I could think of to post
is how some of the things on these forums are connected like:

mostly playing with the reduced LL test today
Code:
2(k)(n)+1 > 2(2(k)(n)+1)^21 > 8(k^2)(n^2)+8(k)(n)+1 > 8(k)(n)(n+1)+8(k^2)+8(k)+1 a(2(k)(n)+1)>2(a(2(k)(n)+1))^21 > (a^2)(2(2(k)(n)+1)^21 >(a^2)(8(k^2)(n^2)+8(k)(n)+1) > (a^2)(8(k)(n)(n+1)+8(k^2)+8(k)+1) a are the values that are s_n divided by the mersenne primes in that form of the test.

The connection between primes and the riemann zetafunction is very exiting. Maybe somethink for you. ;)
Check it out: https://en.wikipedia.org/wiki/Riemann_zeta_function And one more link: https://en.wikipedia.org/wiki/Proof_..._zeta_function Last fiddled with by MisterBitcoin on 20170407 at 12:01

closest to that I have are numberphile videos mostly right now:
it relates to too much for me to deal with and Lfunction stuff exist in PARI/gp but I'm not good enough at knowing what to put in to get anything back useful to me.

twitter update
At least on my account, there's now an option to post 25 tweets in a tweet thread. Each one can contain a poll of up to 4 options. What are some potentially useful topics to poll about, other than worst intersection in a municipality ?

I assume they make their money by selling information about users.
So the question is what you want that information about you to say, perhaps?

I was thinking at one point of making a poll of all 101 products my job placement place makes and seeing what people like. of course I have so few followers, that it probably wouldn't hit any of the bakery's customers.

What's the significance of the fact...
That the residues mod some mersenne in the LL test, are quadratic residues mod the next mersenne.
Reason I think this to be true: Sqr(A*p+b)= A^2(p^2)+ b^2(1^2)b mod 2p+1 and two parts of that simplify to quadratic residues. Failure would only happen if the sums/ differences of quadratic residues wasn't a quadratic residue ( guess I may be wrong). Last fiddled with by science_man_88 on 20180121 at 00:16
