I met Dan once, and asked him about this, since I didn't know what the
symbols mean. He said that it is explained in the book somewhere, and I'm
sure it is, but he wasn't able to find the explanation either, so it seems
to be pretty hard to find.
At any rate, knowing these symbols helps me a lot with the complexity of all
the categories he gives.
