comment When are two algorithms essentially the same?
I fear that upvoting your answer will catch me in a contradiction, insofar as I will be saying that "there will be no satisfactory answer to this question" is a satisfactory answer to the question. But I'll take that risk.

This is definitely not a violation of etiquette.

comment Collatz property implying infinite “fall below” trajectories, is it known?
OK, so what you are asserting is that for every $m$ there exists $n$ such that for every $a$ $T^k(a\cdot2^n+m)<a\cdot2^n+m$ for some $k$, where $T$ is the Collatz iteration, right?

comment Collatz property implying infinite “fall below” trajectories, is it known?
I think you are claiming that for every $m$ there exists $n$ such that for every $a$ Collatz is true for $a\cdot2^n+m$. Is that right?

@Dietrich, there are more where those came from, I think eight examples with $x<1000$.

Note that my earlier comment referred to an earlier version of the question.

$78^3-4\times29^3=614^2$. $93^3-4\times53^3=457^2$.

You posted on m.se and MO without linking each to the other. That's rude.

comment Maximum possible number of similar three colored triangles
I suppose for the $2\times2\times2$ you insist on planarity, else the vertices of a regular octahedron will do.
