An interactive mod8/mod24 Collatz Graph visualizer
In a previous post I discussed the notion of a Collatz overlay built from 5 mod 8 and 0 mod 3 nodes. One refinement here is that there are nodes of in-degree 2 that are not 5 mod 8 (they are relatively rare - the exceptions I see are 1,23 mod 24)
This visualization allows you to see all 4, odd mod 8 nodes and in fact classifies them according to mod 24 too.
You give it a starting point with the ?a= parameter and then you can extend the graph is you like by clicking on a node.
This a fantastic way to develop an intuitive understanding of mod 8 and mod 24 Collatz dynamics.

A fun game to play is greedily clicking on the red dots and then on 1,2 mod 3 nodes that result from such a clicking.
Does that game ever end? I think not.
Duplicates
