Let Fn denote the free group of rank n and write d (G) for the minimal number of generators of the finitely generated group G. In this paper we consider n-generator presentations of groups G with d (G)< n. If G={xx, x2,..., xr| R) then there is an obvious way to make a presentation of G on n> r generators, namely
