The Collatz Conjecture, also known as the $3X + 1$ conjecture, involves taking any positive integer and following a specific set of steps to generate a sequence. The conjecture claims that no matter which positive integer you start with, you will always eventually reach the number $1$. The steps ...
Setup: Let an odd integer $\mathcal{X}$ be represented in the modified form as
$$\{\sum \limits_{M>m} b_M 2^M\} + 2^m - 1$$
where $b_M \in {0,1}$.
I have an insight that all the repeating odd integers in the Collatz-type 5Z+1 sequence end in either $2^1 - 1$ or $2^2 - 1$.
For example: 13 is $2^3+...
C Proof-verification question where the proof is obviously not correct. I think the attempted proof is so far from rigorous that it has no worth being on this site.

Sum and difference of integers on a blackboard
I asked this question a few days ago and some users helped to find solutions for small cases. After the question was closed, I tried to add more context and current progress, but it has always been rejected. The progress made was to a...
