Abstract An algorithm is presented which calculates rings of polynomial invariants of finite linear groups over an arbitrary field K . Up to now, such algorithms have been available only for the case that the characteristic of K does not divide the group order. Some applications to the question whether a modular invariant ring is Cohen—Macaulay or isomorphic to a polynomial ring are discussed.
