A combinatorial category [Pultr (1973, Def. 1.7)] C C is a locally finite category satisfying the unnatural isomorphism property:.
combinatorial model category in nLab
A combinatorial model structure is one that is generated from small data: it is generated from a small set of (acyclic) cofibrations between small objects.
Combinatorics is a field whose main subject (defining its central subfield of enumerative combinatorics) is the study of cardinality of finite sets of data.
