Misc
- Katelyn Doucette completed a visualizer for Fractran space-time diagrams.[1]
Holdouts
- BB(6)
- Discord user Sheep discovered a new Cryptid,
1RB1LA_0LC0RC_1LE1RD_1RE1RC_1LF0LA_---1LE(bbch), similar to Space Needle. A classification of Cryptids is now being worked on, where this machine, for example, could belong to a class of Needles (along with Space Needle).
- Discord user Sheep discovered a new Cryptid,
- BB(7)
- Further filtering by Andrew Ducharme reduced the number of holdouts from 18,036,852 to 17,823,260.[2] (A 1.18% reduction)
- BB(2,5):
- On 1 April 2026, Discord user mammillaria shared a Lean formalisation of the BMO 3 problem and its solution, which he created using Aristotle AI. Then mxdys formalised the result in Rocq using LLMs, reducing the holdout count to 67, with 60 informal holdouts.
- On 2 April 2026, mxdys solved BMO 3 variant
1RB0RA3LA4LA2RA_2LB3LA---4RA3RB(bbch) using an LLM, reducing the formal holdout count to 66. The proofs for BMO 3 and its variant are available at https://github.com/ccz181078/busycoq/blob/BB6/verify/BMO3.v.
- BB(2,6)
- Andrew Ducharme reduced the number of holdouts from 545,005 to 542,325 via Enumerate.py, a 0.49% reduction.
