We describe in terms of generators and relations the ring structure of the
RO(C2β)-graded C2β-equivariant stable stems ΟβC2ββ modulo the
ideal of all nilpotent elements. As a consequence, we also record the ring
structure of the homotopy groups of the rational C2β-equivariant sphere
ΟβC2ββ(SQβ).Comment: 13 page
