@raspberry_boy@cybre.space The Inverse Collatz search is pretty redundant way to eventually (maybe) obtain any number:
1. Start at 1
2. Subtract 1, then divide by 3. If the result is an odd integer, make a new branch with it as base
3. Multiple all branches by 2
4. Repeat 2-3 until you fnd your number!
IFF the Collatz conjecture holds, this should eventually find any number for you! (I think? Just thought of this now) Could also be a pretty fun Lisp problem due to its recursive nature
