  • Five problems in one.

    From pepstein5@gmail.com@21:1/5 to All on Tue Nov 30 12:33:00 2021
    1) Is this position garbled?
    2) What point (if any) am I trying to prove or illustrate when I
    post this cube action problem.
    3) What is the correct cube action.
    4) Since I'm only posting four questions, why did I claim that there
    are five problems here?
