Since 31 is a prime number, any interval of a 31-tone equal scale (31 equal divisions of the octave or 31 equal divisions of a non-octave interval), when stacked, will continue generating new intervals until all 31 tones have been included. Thus, it is ripe for moment of symmetry scalesmithery.
This page lists all moment of symmetry scales in 31edo.

MOS Families of 31edo
The following diagram shows every generator from 1\31 (one degree of 31edo) to 15\31 (15 degrees of 31edo), and two MOS Scales that one can produce with that generator. The bold lines outline a scale with ten or fewer tones; the lighter lines add some more tones. The exact stopping-point of the generation process in these examples is, admittedly, somewhat arbitrary. Scales with a greater number of tones can be produced by continuing the generating process, until all 31 tones have been included.
Pergen Names
Note that many of the names above are outdated or just plain wrong; most of these names are based on temperaments and pre-TANMANS naming schemes. Here are the pergen names for 31edo's rank-2 scales:
- 1\31 = (P8, P4/13)
- 2\31 = (P8, P5/9)
- 3\31 = (P8, P5/6)
- 4\31 = (P8, P11/11)
- 5\31 = (P8, ccP4/15)
- 6\31 = (P8, P5/3)
- 7\31 = (P8, P12/7)
- 8\31 = (P8, ccP5/10)
- 9\31 = (P8, P5/2)
- 10\31 = (P8, ccP5/8)
- 11\31 = (P8, P11/4)
- 12\31 = (P8, c⁵P4/14)
- 13\31 = (P8, P5)
- 14\31 = (P8, c⁵P4/12)
- 15\31 = (P8, ccP4/5)
