[cmsmqydo] More cards

Combinatorial structures and objects could be nice bases for a deck of playing cards.  The cards relate to one another by their combinatorial interpretation.  The card face illustrates the combinatorial structure.

Bell numbers: 52 partitions of a set of 5.
Catalan numbers: 42 non-crossing partitions of 5.
Partition function (number theory), Young diagram, Young's lattice, Young tableau, p(11) = 56.
Central binomial coefficient: binomial(8,4)=70.
Fibonacci sequence: F(10) = 55, though not sure how to illustrate this one.

2 of each card (2 suits) might be better.
