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

Holdouts

• BB(6): 1e14 machines: 176. 1e15 machines: 240. 9 solved machines.
  • Holdouts lists for machines not simulated to 1e14 and 1e15 steps were created. The holdouts list count is 178 and 240 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 240.
  • Andrew Ducharme solved two machines using FAR.
  • prurq found two machines [1][2] to be Translated Cyclers. Shawn Ligocki verified one of them and discovered its preperiod to be over $10^{12}$ steps. mxdys verified the other. Both were 1e14 and 1e15 holdouts, thus reducing those holdout counts by 2.
  • mxdys found four more [3][4] Translated Cyclers in the remaining holdouts and solved one more TM using FAR.
