  1. How about the square inscribed in the diamond?

  2. A natural question…
    In modal theology (Anselm, etc.), God is a necessary being. Hence, given the standard symbolism of modal logic, God might appropriately be represented by a square. A square within a diamond might, therefore, represent a modal theistic argument— a proof of the existence of God which makes use of the premise that God is a being who exists in every possible world.

  3. Very interesting. Yet the square within a diamond isn’t represented among the possible 48 matrix group actions?

  4. Sorry, the 3×3 array is too small for that… Unless you rotate it by 45 degrees.

  5. OK, so I just read a Czech article about International Women’s Day, and the verdict is that many people think it’s communist BS and other people see it as older and bigger than communist regimes, which it apparently is. I have learned something.
