Abstract
Motivated by juggling sequences and bubble sort, we examine permutations on the set { 1 , 2 , … , n } with d descents and maximum drop size k . We give explicit formulas for enumerating such permutations for given integers k and d . We also derive the related generating functions and prove unimodality and symmetry of the coefficients.
