{{TM|1RB0LC_1LC0RD_1LF1LA_1LB1RE_1RB1LE_---0LE}} is a [[probviously]] halting tetrational [[BB(6)]] [[Cryptid]] found by Racheline on 23 Nov 2024 ([https://discord.com/channels/960643023006490684/1239205785913790465/1310044618632593409 Discord link]).

<blockquote>
1RB0LC_1LC0RD_1LF1LA_1LB1RE_1RB1LE_---0LE is a tetrational probviously halting cryptid. the lower bound for when it halts is around 10^10^120395, and with each exponentiation it has a 1/4 chance of halting, so i think the expected halting time is around 10^10^10^10^10^120395
sadly we won't be able to run it any further, it uses the hydra map which we don't have a way to accelerate
