Abstract
We define an excedance number for the multi-colored permutation group i.e. the wreath product (ℤr1 × ⋯ × ℤrk) Sn and calculate its multi-distribution with some natural parameters. We also compute the multi-distribution of the parameters exc(π) and fix(π) over the sets of involutions in the multi-colored permutation group. Using this, we count the number of involutions in this group having a fixed number of excedances and absolute fixed points.
