Let S be a nonempty finite set with cardinality m. Let M be a matroid on S with no loops. The covering number of an element x in S is the smallest positive integer k such that x is a coloop of the union of k copies of M. We investigate connections between the structure of M and the values of the cov

A partition u of [k] = {1, 2, . . . , k} is contained in another partition v of [l] if [l] has a k-subset on which v induces u. We are interested in counting partitions v not containing a given partition u or a given set of partitions R. This concept is related to that of forbidden permutations. A s
