Geoffrey Irving strongly solved Pentago in 2014 using a Cray supercomputer at NERSC, computing values for all 3,009,081,623,421,558 positions after symmetry reduction and showing the first player wins. The full database is browsable online at perfect-pentago.net.
Pentago (6x6) is a first-player win with perfect play, and the value of every position is known.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
