'''19683/19208''', the '''skwares comma''', is a [[7-limit]] and [[2.3.7 subgroup]] comma of about 42 cents. It can be defined as the difference between a perfect eleventh ([[8/3]]) and a stack of four [[9/7]] supermajor thirds. In the [[2.3.7.11 subgroup]], it decomposes into ([[99/98]])<sup>2</sup> × [[243/242]], and in the full [[7-limit]], it decomposes as ([[81/80]])<sup>2</sup>/([[2401/2400]]). | |||
In the 2.3.7 subgroup, this comma defines '''skwares''' temperament, whose obvious extensions to primes 5 ([[squares]]) and 11 are dictated by the above decompositions. | |||
