- another approach would be to avoid linear representations and instead seek subgroups H of the 16-element quasidihedral group G, which give actions of G on the finite sets G/H. To satisfy julesh (npub1whr…qc2t) we'd want H to have 2 elements, so G/H would be an 8-element set. There's an obvious 2-element subgroup H ⊆ G consisting of 𝐼 and 𝑠, and this G/H may be Jules' "twisted octagon".
