I know this geometrical ordering of the numbers of trumps, courts and pips for a wile, and consider it a very interting theory.

My question is this: Can there any mathematical resources be named for the presence, discussion and evaluation of this geometric figure, its substructures, and its neo-pythagorean background in the 14th and 15th century?

And is there any historical connection that could be offered to show that such a relation could have any evidence in these times?

Since I am reasearching the problem of the "22" trumps myself right now intensly, I would be very interested...
