In this paper we study Euler's difference table associated to the sequence $\\{\\ell^n n!\\}$ and the generalized derangement problem. For the coefficients appearing in the later table we will give the combinatorial interpretations in terms of two kinds of $k$-successions of the group $C_\\ell\\wr S_n$. In particular for $\\ell=1$ we recover the known results for the symmetric groups while for $\\ell=2$ we obtain the corresponding results for the hyperoctahedral groups.", "revisions": [ { "version": "v1", "updated": "2008-10-15T15:28:28.000Z" } ], "analyses": { "keywords": [ "hyperoctahedral groups", "combinatorial interpretations", "symmetric groups", "study eulers difference table", "generalized derangement problem", "derangements", "wreath product" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0810.2727F" } } }
