It is intended to allow people to avoid repetitive arguments such as "is 400¢ a 5/4?" by identifying the base assumptions that allow answers to be different. The proposal by User:Ground for some abbreviations, avoiding those commonly seen in a xenharmonic context like MT for meantone and ET for equal temperament: # '''D: Direct'''. All rati...")

Normally the subgroup is interpreted as 2.3.5, but 2.9.5 is also possible. This provides a great opportunity for straddling 3, where flat 3 (3/a in SRTT) and sharp 3 (3a) cancel out to make 9. Of the Diaschismic extensions to the 7-limit, Septimal Diaschismic tempers out 126/125, another 2.9.5.7 comma, and Pajara uses the sharp 3, tempering out 64/(3a*7) = 64/63 a^-1. Th...")
