Let G be a finite group. Let Irr(1)(G) be the set of nonlinear irreducible characters of G and cd(1)(G) the set of degrees of the characters in Irr(1)(G). A group G is said to be a D-2-group if vertical bar cd(1)(G)vertical bar = vertical bar Irr(1)(G)vertical bar - 2. The main purpose of this paper is to classify nonsolvable D-2-groups.
