We consider a finite dimensional representation of the dihedral group D 2p over a field of characteristic two where p is an odd integer and study the corresponding Hilbert ideal I H. We show that I H has a universal Gröbner basis consisting of invariants and monomials only. We provide sharp bounds for the degree of an element in this basis and in a minimal generating set for I H. We also compute the top degree of coinvariants when p is prime. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
