-The 11-state, 2-symbol Busy Beaver problem, BB(11,2), is unsolved and unexplored. The current BB(11) [[champion]] is {{TM|1LH1LA_1LI1RG_0RD1LC_0RF1RE_1LJ0RF_1RB1RF_0LC1LH_0LC0LA_1LK1LJ_1RZ0LI_0LD1LE|halt}}, which takes over <math> f_\omega^2(2 \uparrow\uparrow 12)</math> steps to halt. It was dicovered by Racheline in 2024. Due to the discovery of [[Antihydra]] in [[BB(6)]], the existence of [[Collatz-like]] [[Cryptids]] in BB(11) is certain.

-Based on a sample enumeration of [[BB(8)]], BB(11) is expected to be very difficult to enumerate.
