This Month in Beaver Research for February 2026. TODO: Write a proper introductory paragraph.

Holdouts

• BB(6): 1e14 machines: 178. 1e15 machines: 242. 3 solved machines.
  • Holdouts lists for machines not simulated to 1e14 and 1e15 steps were created. The holdouts list count is 178 and 242 respectively. See Spreadsheet for BB6.
  • Later, prurq found 10 more machines in the holdouts list that had previously been simulated to 1e15: thus the new 1e15 holdout count is 242.
  • Andrew Ducharme solved two machines using FAR.
  • prurq found a machine to be a Translated Cycler. Shawn Ligocki verified this and discovered the preperiod to be over $10^{12}$ steps.
  • mxdys found four more [1][2] Translated Cyclers in the remaining holdouts and solved one more TM using FAR.
