Query: Classifying Dihedral O(2)-Equivariant Spectra   The category of rational O(2)-equivariant spectra splits as a product of
cyclic and dihedral parts. Using the classification of rational G-equivariant
spectra for finite groups G, we classify the dihedral part of rational
O(2)-equivariant spectra in terms of an algebraic model.
