It has got me wondering how many different ways can someone arrange the cards to get different 4x4 squares that meet the condition that no row or column can have the same suit or rank. As far as a 5x5 square.. this wouldn't work with the paying cards since there are only 4 suits. Putting a fifth card in any row or column automatically guarantees that there will be a duplicate suit in that row or column.

Only thing missing here is a description of how you did make them as opposed to just how you did not. I think the contrast in the first from the second might be interesting in particular.
