[Shawn Ligocki]

TMBR (This Month in Beaver Research, "timber") for November 2025 is now available:

https://wiki.bbchallenge.org/wiki/TMBR:_November_2025

This month we continue to see progress in many different directions. @mxdys reduced the BB(6) holdout count by 12% to 1416 (very significant progress with a list this small and pored over). There was significant exploration into Busy Beaver functions for alternative models of computation including Fractran and Cyclic Tag systems. Furthermore, both Tristan and Carl gave talks about Busy Beaver. This month we added Shen Lin to the wiki as our first article about a person.
