Hi again folks. I've started making a few other diamonds as per Dave's suggestions, and by doing so I found 4 errors in the notations of 7/5 and 7/15, where in G
the 7-commas should have been downward instead of upward, i.e. G
, and in ratios 35/5 (=7/1), 35/15 (=7/3), 5/35 (=1/7), 15/35 (=3/7), where for some reason I'd written symbols for way different ratios what looks like 81:64 apart... No idea why that might be, but hopefully most of the silly mistakes have been fixed now.
I've attached a version with these errors corrected, as well as what I think is a correct Herculean precision 13-prime 45-limit diamond (no minas). I'm working on a similar Athenian diamond now.
