Unsolved problem:
Does this TM run forever?
1RB0LB_1LC0RE_1LA1LD_0LC---_0RB0RF_1RE1RB (bbch) is a probviously non-halting BB(6) Cryptid found by @racheline and shared on Discord on 25 Nov 2024.
Rules
start: (4,124) (a+1,3n+0) --> (a+7,4n+4) (a+1,3n+1) --> (a+0,4n+7) (a+1,3n+2) --> (a+5,4n+4) (0,3(27n+21)+1) --> halt (a,n) := 0^inf 10 01^a 0^n <A 11011 0^inf
For simplicity only one potential halting rule is shown. In fact, it also has the potential to become a translated cycler or bouncer when it reaches (0,n).

If the starting state is set to B and put into TNF, the TM becomes 1RB0LD_1RC1RF_1LA0RA_0LA0LE_1LD1LA_0RB--- (bbch).
