As per Dave and others' suggestions, I've made a few revised diamonds, only involving the primes up to 13, but extending the odd limit to also include ratios of 45, which can be pretty important.

This one's Athenian-level precision, so small intervals like the 13-schismina ("mina") and 5-schisma are effectively "virtually tempered out", that is, notationally ignored, so that 5/4 from D can be notated as either F or as G (with schismas, usually G)

The Athenian set also uses quite a few less symbols, so no for anyone interested, those are all simplified to Athenian precision symbols.

Hope there are no errors in this one, just been through my other two diamonds and found quite a few little mistakes, mostly involving accidentally reversing up- and down-shafts.
