Circle diagram.

A 13-odd-limit Hexany. This creates a scale of 1 11/10 11/9 13/10 13/9 143/90 2/1, with steps of 11/10 10/9 117/110 10/9 11/10 180/143. This is a mildly compressed whole tone scale with a gap of 400 cents at the end and quite melodically effective, as no interval is too small to be hard to distinguish from its neighbours. Although it has no 5ths, many of its notes are close enough to 12edo major and minor thirds to provide some degree of familiarity and create stable dyads to root upon.
