151263/151250, the odiheim comma, is an unnoticeable 11-limit comma. It is expressible as (2401/2400)/(3025/3024), and also represents the difference between 63/50 and a stack of two 55/49's, which is notable due to 55/49 being a very good approximation of one step of 6edo, and 63/50 being the same for 3edo; therefore this comma is tempered out in a number of 6th-octave temperaments.
Temperaments
It is tempered out by notable edos like 270edo, 342edo, 1578edo and 1848edo.
Etymology
