This Month in Beaver Research for November 2026.
BB Adjacent
- Pebble Automaton
- On November 2, User:AlephSquirrel found the golems, a group of 22 pebble(11) holdouts modeled by complex systems of equations, making them potential cryptids. They can be categorized into 7 unique paths.

- On November 1, Ahmer Reza simulated two holdouts, both Reus Vampires, to halting.[3]
Cryptids
All Turing machines mentioned in this section work with an alphabet of 2 symbols unless explicitly stated. The state bounds given also only consider Turing machines which work with 2 symbols.
- Cryptids in the Wild (+ Energy Vampires)
- Reus Vampires
- On November 1, Ahmer Raza ran path O4 to 1,941,376,761,248 iterations, at which point it halts![4] This path corresponds to a group of machines with halting times of over 10683,718,950,000 steps, and decides the last of the 7 Reus vampires.
- Larger Cryptids
- Logical Independence
- Zermelo-Frankel set theory
- On November 1, charlie claimed to have used Claude to formally reduce the number of defined instructions required in a ZFC-independent TM to 375 (376 including the halting transition).
- Computational Complexity Theory
- On November 1, GregoryMorse claimed to have found a 278-state machine that quasihalts iff P = NP, a 295-state machine that quasihalts iff P = PP, and a 291-state machine that quasihalts iff P = PSPACE.[5]

Unknown - pseudoquasihalts if the conjecture is false. Proof.
