## Abstract

The Hecke algebra of the pair (S_{2n},B_{n}), where B _{n} is the hyperoctahedral subgroup of S_{2n}, was introduced by James in 1961. It is a natural analogue of the center of the symmetric group algebra. In this paper, we give a polynomiality property of its structure coefficients. Our main tool is a combinatorial universal algebra which projects on the Hecke algebra of (S_{2n}, B_{n}) for every n. To build it, we introduce new objects called partial bijections.
