We derive multivariate generating functions that count signed permutations by various statistics, using the hyperoactahedral generalization of methods of Garsia and Gessel. We also derive the distributions over inverse descent classes of signed permutations for two of these statistics individually (

โฆ Synopsis
We derive a multivariate generating function which counts signed permutations by their cycle type and two other descent statistics, analogous to a result of Gessel and Reutenauer [4,5] for (unsigned) permutations. The derivation uses a bijection which is the hyperoctahedral analogue of Gessel's necklace bijection.

In this paper we exploit binary tree representations of permutations to give a combinatorial proof of Purtill's result [8] that where A n is the set of Andrรฉ permutations, v cd (ฯ ) is the cd-statistic of an Andrรฉ permutation and v ab (ฯ ) is the ab-statistic of a permutation. Using Purtill's proof
For any dimension d and any k = 1 .... ,d we construct a 2-neighborly triangulation of a d-manifold Mk a which is invariant under the action of the dihedral group D, on n = 2d-k(k + 3) --1 vertices. Mk n is the boundary of a (d + 1)-manifold Mdk+l with the same properties. Special cases in this fami
In this paper the author constructs universal cycles of 3-subsets of an n-set for n 28 and (n, 3)= 1, verifying a conjecture of Chung et al. ( ) for 3-subsets. Universal cycles of 4-subsets of an n-set for n > 8 and (n, 4) = 1 are also constructed, partially solving the same conjecture for 4-subsets
We define new Mahonian statistics, called MAD, MAK, and ENV, on words. Of these, ENV is shown to equal the classical INV, that is, the number of inversions, while for permutations MAK has been already defined by Foata and Zeilberger.
