Abstract

The coefficients of g^(^s^) in expanding the rth derivative of the composite function g@?f by Faa di Bruno's formula, is determined by a Diophantine linear system, which is proved to be equivalent to the problem of enumerating partitions of a finite set of integers attached to r and s canonically.
