The marveltwin comma, 325/324, is a 13-limit (also 2.3.5.13 subgroup) comma measuring about 5.3 ¢. Its significance is in that it can be expressed as (10/9)2/(16/13), (25/18)/(18/13) and (25/24)/(27/26), among other expressions.
It factors into (625/624)(676/675), (385/384)(2080/2079), (364/363)(3025/3024), (352/351)(4225/4224), or (351/350)(4375/4374).
Tempering it out leads to the rank-five marveltwin temperament, which identifies 16/13 by two 10/9's stacked.
