1. I said that the Sigma sides are lower than Pi sides, all things
being equal. That was an error. The Pi sides are lower than the Sigma
sides. That takes care of the particular kind of example that you

set theoretic questions, in order, and even experiment with that
Is Con(ZFC) your favorite mathematical question? It's not a
mathematical question at all, or if it is one, it's probably not your
favorite one. I also mentioned that one can list these mathematical set
theoretic questions in order of, say, Google Scholar hits.
