1-3-7-11 by 18/11 bihexany

An 11-odd-limit Bihexany. This creates a scale of 1 9/8 7/6 21/16 11/8 63/44 3/2 77/48 18/11 7/4 11/6 21/11 2/1, with steps of 9/8 28/27 9/8 22/21 126/121 22/21 77/72 864/847 77/72 22/21 126/121 22/21. This cancels out some of the ratios in the base hexany and expands the number of perfect fifths from 2 to 6, giving you plenty of simple but xenharmonic chords and only one step that is small enough to be melodically dubious.
