The '''olympia''' ([[monzo]]: {{monzo| 17 -5 0 -2 -1 }}, [[ratio]]: 131072/130977), otherwise known as the '''olympic comma''', is an [[11-limit]] (~~also~~ 2.3.7.11 [[subgroup]]) [[~~unnoticeable~~ comma]] measuring about 1.26 [[cent]]s. It is the difference between the undecimal quartertone ([[33/32]]) and a stack of two septimal commas ([[64/63]]). Even more interesting is the ~~possible~~ factorization into two [[13-limit]] [[superparticular]] ~~ratios~~: ([[2080/2079]])([[4096/4095]]). ~~In fact,~~ the olympia is the default ~~interval~~ represented by three [[mina]]s in the Olympian level of [[Sagittal notation]], from which it gets its name.

The '''olympia''' ([[monzo]]: {{monzo| 17 -5 0 -2 -1 }}, [[ratio]]: 131072/130977), otherwise known as the '''olympic comma''', is an [[unnoticeable comma|unnoticeable]] [[11-limit]] (specifically [[2.3.7.11 subgroup|2.3.7.11-]][[subgroup]]) [[comma]] measuring about 1.26 [[cent]]s. It is the difference between the undecimal quartertone ([[33/32]]) and a stack of two septimal commas (([[64/63]])<sup>2</sup>). Even more interesting is the factorization into two [[13-limit]] [[superparticular ratio]]s: ([[2080/2079]])⋅([[4096/4095]]). These ratios and the olympia itself are the default intervals represented by one, two, and three [[mina]]s in the Olympian level of [[Sagittal notation]], from which it gets its name.

== Temperaments ==

Tempering out this comma in the full 11-limit results in the rank-4 '''olympic temperament''' , with a very natural 13-limit extension {2080/2079, 4096/4095} (→ [[Rank-4 temperament #Olympic (131072/130977)]]).

As its order of 11 is one, any 7-limit temperament can be extended to the 11-limit by tempering out this comma. To make practical sense, however, it requires low complexity and high accuracy of the septimal comma, which is less common.

== Etymology ==

The olympia was named by [[Flora Canou]] in 2021, referring to the Olympian level of Sagittal notation.
