==Elfjove7==
==Elfjove7==
[[Elfjove7]] is the seven note elf scale of jove temperament, the 11-limit temperament rank three tempering out 243/242, 441/440, 540/539 and 2401/2400. In the 202et tuning, it has steps 0, 39, 59, 84, 118, 143, 163, 202, with a consonance set {25, 28, 31, 34, 39, 45, 53, 59, 65, 70, 73, 84, 93, 98, 104, 109, 118, 129, 132, 137, 143, 149, 157, 163, 168, 171, 174, 177}. The permutation group of automorphisms is intransitive, with orbits {0}, {1, 6} and {2, 3, 4, 5}. The group is the group of the square, acting transitively on the {2, 3, 4, 5} orbit, and exchanging 1 and 6 when the permutation of 2345 is even.

Elfjove7 has three maximal cliques, the pentad 02345 and the two tetrads 0135 and 0246. The scale is a tempering of the transversal 1-8/7-11/9-4/3-3/2-18/11-7/4-2, and so the maximal cliques are temperings of 1-11/9-4/3-3/2-18/11, 1-8/7-4/3-18/11 and 1-11/9-3/2-7/4, which are essentially tempered chords.
