## Abstract We consider oneβfactorizations of __K__~2__n__~ possessing an automorphism group acting regularly (sharply transitively) on vertices. We present some upper bounds on the number of oneβfactors which are fixed by the group; further information is obtained when equality holds in these boun

β¦ Synopsis
In this paper we study the flat maps from a finile graph G to a Euclidean space I? that were recentlq defined and studied in [4]. We define the vertex dimension of a finite graph and give some necessary conditions for a polygonal map to be flat. As a result we show that the vertex dimension of the complete graph on 21 vertices equals I.

The euclidean dimension of a graph G, e(G), is the minimum n such that the vertices of G can be placed in euclidean n-space, R", in such a way that adjacent vertices have distance 1 and nonadjacent vertices have distances other than 1. Let G = K(n,, . , ns+,+J be a complete (s + t + u)-partite graph
