151263/151250, the odiheim comma, is an unnoticeable 11-limit comma. It is expressible as (2401/2400)/(3025/3024), and is also the difference between 63/50 and a stack of two 55/49's. 55/49 is very close to 1\6, and 63/50 to 1\3, so this comma is tempered out in a number of 6th-octave temperaments (although it does not define such temperaments on its own).
Temperaments
It is tempered out by notable edos like 270edo, 342edo, 1578edo and 1848edo.
Etymology
This comma was presumably named by Gene Ward Smith in 2011 since it seems this wiki was the place where it made its first appearance[1]. The name is a contraction of odin and heimdall, the two notable rank-3 temperaments where the comma is tempered out.
