'''248/243''' is a [[31-limit]] medium-sized [[comma]]. This interval is significant in the [[Functional Just System]] as the formal comma to translate a Pythagorean interval to a nearby tricesimoprimal (31-limit) interval. Consequently, [[31/16]] is represented as a major seventh. In the [[Helmholtz-Ellis notation]], however, that role is taken by [[32/31]], so 31/16 is represented as an octave.

248/243 is a 31-limit medium-sized comma. This interval is significant in the Functional Just System as the formal comma to translate a Pythagorean interval to a nearby tricesimoprimal (31-limit) interval. Consequently, 31/16 is represented as a major seventh. In the Helmholtz-Ellis notation, however, that role is taken by 32/31, so 31/16 is represented as an octave.
