~~Revopentisma~~ is a 7-limit (~~and also~~ 2.3.7 subgroup) ~~unnoticeable~~ comma associated with very high accuracy temperaments.

The '''revopentisma''' is an [[unnoticeable comma|unnoticeable]] [[7-limit]] (specifically [[2.3.7 subgroup|2.3.7-subgroup]]) [[comma]] associated with [[very high accuracy temperaments]].

== ~~Theory~~ ==

~~Revopentisma~~ is the comma shared by [[31edo]] and [[~~270edo~~]] in the [[2.3.7 subgroup]] and is notable as ~~supported~~ by many [[mega-edo]]s. ~~The [[Very high accuracy temperaments#Revopentic (~~2.3.7~~)|associated temperament~~]] is ~~named '''revopent''', and it's~~ remarkable in its short generator chains for edos in the thousands, with 7/4 being just four generators ~~down~~ and 3/2 being just nineteen, with octave reduction~~. Tempering it out in the full 7-limit produces rank-3 '''revopentismic''' temperament, as well as the 2.3.7 rank-2 '''revopentic''' temperament~~. The ~~rank-2~~ revopent temperament adds mapping for 5 where it is reached in 287 generators.

== Temperaments ==

The revopentisma is the comma shared by [[31edo]] and [[135edo]] in the [[2.3.7 subgroup]] and is notable as [[support]]ed by many [[mega-edo]]s. Tempering it out in the full 7-limit produces rank-3 '''revopentismic''' temperament, as well as the 2.3.7 rank-2 [[revopentic]] temperament. The latter is remarkable in its short generator chains for edos in the thousands, with [[7/4]] being just four generators away and [[3/2]] being just nineteen, with octave reduction. The [[revopent]] temperament adds mapping for 5 where it is reached in 287 generators.

== Etymology ==

~~Comma's name is~~ derived from two ~~edos in the~~ temperament~~-merging~~, number 1848 being associated with a year with a large number of revolutions in Europe, and 3125 being equal to 5 to the power of 5, hence pent- meaning five.

This comma was named by [[Eliora]] in 2023, and was derived from two of its supporting [[equal temperament]]s, number 1848 being associated with a year with a large number of revolutions in Europe, and 3125 being equal to 5 to the power of 5, hence pent- meaning five.
