摘要：
For r = 7 and 8 we consider an action of the Weyl group of type Er on a unimodular lattice of rank r + 1. We give the tables of the first cohomology groups for all cyclic subgroups of the Weyl group with respect to this action. These are important in the arithmetic theory of Del Pezzo surfaces.
