%N Maximal degree of an irreducible representation of the group of n X n signed permutation matrices.

%C This group is also the automorphism group of the n-dimensional hypercube and the wreath product of the cyclic group C_2 and the symmetric group S_n.

%C The number of irreducible representations is given in A000712; the order of the group in A000165.

%C The group is also the Weyl group of type B_n. - _Eric M. Schmidt_, Sep 21 2013
