==Orwell[13]==

Orwell[13], ~~yhe~~ 13-note MOS of orwell, has four more notes but the same set of 11-limit consonances as Orwell[9]. Now we have 0, 5, 7, 12, 17, 19, 24, 29, 34, 36, 41, 46, 48, 53, and while the graph of the scale still has a lot of symmetry, it is of an entirely different kind. This time the symmetry group is analogous to that of the diatonic scale, being the dihedral group D26 on 13 points. Orwell[13] has 26 maximal pentads and 13 maximal hexads on which the automorphism group faithfully acts.
