This one is trivial. If the square number is even, it must be divisible by 2, and also 4, as all powers of prime divisors of squares must be even for it to be a square number. If you take a square s...

The conjecture originally was that these prime loops (p -> 2p -> 2p) are the only loops and that all numbers terminate in such a loop. @henryzz pointed out more formats (actually a pattern for...

Let me correct you.



I was explaining my improved version of the original rule for the sequence. Thus 75 goes to 50. At least in my version, that is.

75 = 3 * 5^2, that is 6 divisors, 6 = 2...

For a moment I thought about using only the proper divisors, but this lead me very quickly to a realization of a problem with primes, which would then have only 1 divisor.

These number series are...

Are plurals allowed? If so, then:

e[8]: effervescencelessnesses
i[7]: indivisibilities

However, these might be grammatical non-sense.
