Abstract

The hyperoctahedral group HNH_N is known to have two natural liberations: the "good" one HN+H_N^+, which is the quantum symmetry group of NN segments, and the "bad" one OˉN\bar{O}_N, which is the quantum symmetry group of the NN-hypercube. We study here this phenomenon, in the general "quizzy" framework, which covers the various liberations and twists of HN,ONH_N,O_N. Our results include: (1) an interpretation of the embedding OˉNS2N+\bar{O}_N\subset S_{2^N}^+, as corresponding to the antisymmetric representation of ONO_N, (2) a study of the liberations of HNH_N, notably with the result <HN+,OˉN>=ON+<H_N^+,\bar{O}_N>=O_N^+, and (3) a comparison of the kk-orbitals for the inclusions HNHN+H_N\subset H_N^+ and HNOˉNH_N\subset\bar{O}_N, for kNk\in\mathbb N small.
