{{TM|1RB0RC_0LC0LB_0LD1LC_0LE1LA_0LF---_1RF1RA|halt}} is a halting [[BB(6)]] Turing machine found by Racheline on 30 July 2024 ([https://discord.com/channels/960643023006490684/1239205785913790465/1267805112651350107 Discord link]). It is similar to {{TM|1RB1LE_0LC0LB_1RD1LC_1RD1RA_1RF0LA_---1RE}} in the sense that it follows tetrational Collatz-like rules which allow it to either become a [[translated cycler]] or to halt. However, it does not run long enough to be a [[Cryptid]]. Racheline was able to simulate it long enough to prove that it halts in about <math>10^{33\,561\,633}</math> steps.
