Monster Group Fun

Fun with Monster Primes: (Please hit reply to see it correctly):

C D E F G A Bb B
72
32 42 48 60
18 20 24 30
8 12 14
4 6
3

These are based on the 15 primes in the Monster, with one added to
each:

2,3,5,7,11,13,17,19,23,29,31,41,47,59 and 71

One added: 3,4,6,8,12,14,18,20,24,30,32,42,48,60 and 72

Now look at G7 and C7 Chords:

G7: 12 15 18 21
C7: 4 5 6 7

Which get used?

G7 3
6
12 18
24 30 42
48 60 72

C7 3
4 6
8 12 14
20 24
32 48

This relates to supersingular primes, and in a sense, superparticular
ratios, because you need to go one below to get the primes of the
Monster group.

(I know, not that relevant to tuning, but it has been slow lately...)
