Define the transportation polytope T n,m to be a polytope of non-negative n × m matrices with row sums equal to m and column sums equal to n. We present a new recurrence relation for the numbers f k of the k-dimensional faces for the transportation polytope T n,n+1 . This gives an efficient algorith

✦ Synopsis
asked for estimates for the number of equivalence classes of lattice polytopes, under the group of unimodular affine transformations. What we investigate here is the analogous question for lattice free polytopes. Some of the results: the number of equivalence classes of lattice free simplices of volume at most v in dimension d is of order v d-1 , and the number of equivalence classes of lattice free polytopes of volume at most v in dimension d is O(v 2 d -1 (log v) d-2 ).

We prove two new upper bounds on the number of facets that a d-dimensional 0/1-polytope can have. The first one is 2(d -1)!+2(d -1) (which is the best one currently known for small dimensions), while the second one of O((d -2)!) is the best known bound for large dimensions.
We study some polynomials arising from Whitney numbers of the second kind of Dowling lattices. Special cases of our results include well-known identities involving Stirling numbers of the second kind. The main technique used is essentially due to Rota.
In this paper, a formula is given for the Mo bius number +(1, S n ) of the subgroup lattice of the symmetric group S n . This formula involves the Mo bius numbers of certain transitive subgroups of S n . When n has at most two (not necessarily distinct) prime factors or n is a power of two, this for
