You've linked the GeoGebra file, but you really should also provide a link to the Python code. I would really like to play around with that version.

I'm surprised this doesn't attract more attention, if only because it would imply there are trajectories that can flawlessly avoid primes without being a trivial sequence of multiples. If there are numbers that trend to infinity, then the patterns they follow would be another insight into the patterns that primes follow

this feels very similar to the 2n+1/Collatz conjecture

Infinitesimals might be useful, but infinitesimals are NOT the opposite of infinity. There is nothing larger than infinity. There is nothing smaller than zero. Zero is the opposite of infinity, if that could be defined at all.

Given that the divisors are paired up and the number itself isn't included, why is 1 always included as a divisor? If it were ignored, the whole theory would change.

If those truely are counterexamples, so computing power ever will help us recognize them as such, since the sequence would go on foreever. We would have to recognize patterns in the sequence, that let us prove that the sequence has to go on forever.

I like to imagine that 276 goes all the way up straight to the first and only odd perfect number, and that number also happens to be the first number to start a loop that disproves the collatz conjecture.

Interesting that three of those five unsolved numbers are multiples of 138. (2, 4, and 7?). Is that a recurring thing with the mystery numbers over 1000?

I first learned about amicable numbers from Martin Gardner's Scientific American article. It is reprinted in his book, "Mathematical Magic Show," in the chapter entitled, "Perfect, Amicable, Sociable." That chapter does not contain the term "aspiring"; this omission may partially explain why so many people (including myself) know the terms "amicable" and "sociable" but not "aspiring."

I spent a few years factoring aliquot sequences with my computer in its spare time. It can be a lot of fun to see the sequences progress and learn the math of the ups and downs as well as the factoring algorithms and tools.

Does that mean if the aliquot sequence of 276 is a counter-example, there are infinitely many counterexamples, as the infinitely many terms in the aliquot sequence of 276 would also be a counter-example?
@hyperbaroqueКүн бұрын
I conjecture that these will only run on finitely. You will find longer runs and extraordinarily longer runs, but not one that runs one infinitely with also the characteristic of unpredictable peaks and trends. Therefore, this function will never prove to be a stochastic generator. Therefore, this function is by niche studies excluded from the hyporthetical headers and libraries (ANSI-C, of course,) of seudo-scientific-deity "Roko's Basilisk".
