Abstract
For r = 7 and 8 we consider an action of the Weyl group of type E(r) o
n a unimodular lattice of rank r + 1. We give the fables of the first
cohomology groups for all cyclic subgroups of the Weyl group with resp
ect to this action. These are important in the arithmetic theory of De
l Pezzo surfaces.
