Uiua
I thought this was going to be trivial to implement in Uiua, but I managed to blow the stack, meaning I had to set an environment variable in order to get it to run. That doesn’t work in Uiua Pad, so for any counts larger than 15 you need to run it locally. Built-in memoisation though so that’s nice.
# NB Needs env var UIUA_RECURSION_LIMIT=300
Next ← ⍣([1] °0|[×2024] °1◿2⧻°⋕.|⍜°⋕(↯2_∞))
Count ← |2 memo(⨬(1|/+≡Count¤-1⊙Next)≠0.) # rounds, stone
≡(&p/+≡Count¤: ⊜⋕⊸≠@\s "125 17")[25 75]
