### Abstract:

Struct is an algorithm being developed by the authors to

guess the structure of a set of permutations. In some cases the structure

discovered is sufficient to infer the generating function of the set and

provides an enumeration of the permutations by length. A preliminary version of

the algorithm will be presented and applied to several sets of permutations.
