We establish a recurrence relation to enumerate the sequences with given sum and last term and derive methods for constructing all such sequences with a given sum.

Comma-free codes and incidence algebras,dering the binary relation the code defines on its alphabet. If the code is a maximal comma-free code we show that the relation it defines is the support relation of an incidence algebra and its complementary relation will also define an incidence algebra.

Number of factors in K-cycle decompositions of permutations,k-cycles. Denote by f.(π) the minimal number of k-cycles required for such a representation. In this paper bounds for f.(π) are derived. These bounds are used to determine . for all k, where f.(n)=max{f.(π) | π ε S.}.

A theorem on planar graphs,orial map theory from such a definition is still needed, however, as some theorems which are intuitively obvious topologically are not so clear combinatorially. In this paper, a combinatorial proof is provided for one such theorem.

Thomas Curie PhD,Paul Franken PhDGeneric algebra methods are used to translate combinatorial results about Weyl groups into statements about classical groups. A consequence is the maximal nature of the rank of the incidence matrix of isotropice-subspaces vs isotropic f-subspaces of a finite vector space V with a form F, in many cases.
