The object of this paper is to study how many essentially different common transversals a family of convex sets on the plane can have. In particular we consider the case where the family consists of pairwise disjoint translates of a single convex set.

The refined Stirling numbers of the first kind specify the number of permutations of n indices possessing m i cycles whose lengths modulo k are congruent to i; i ΒΌ 0; 1; 2; . . . ; k Γ€ 1: The refined Stirling numbers of the second kind are similarly defined in terms of set-partitions and the cardi
