Interest in combinatorial interpretations of mathematical entities stems from the convenience of the concrete models they provide. Finding a bijective proof of a seemingly obscure identity can reveal unsuspected significance to it. Finding a combinatorial model for some mathematical entity is a particular instance of the process called "categorification". Examples include the interpretation of N as the Burnside rig of the category of finite sets with product and coproduct, and the
