'''151263/151250''', the '''odiheim comma''' or '''odiheim''', is an [[11-limit]] unnoticeable 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]].

== History ==
== Etymology ==
This comma has been listed as “odiheim” on the “[[unnoticeable comma]]” page, ever since the day that page was created in October 2016.
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<ref>[https://en.xen.wiki/index.php?title=Small_comma&oldid=13535 See ''Small comma'' (Revision as of 17:07, 30 June 2011 by Wikispaces>genewardsmith)]</ref>. The name is a contraction of [[odin]] and [[heimdall]], the two notable rank-3 temperaments where the comma is tempered out.  


That page never specified who coined the name, nor did it say why the name was given or if/how it relates to the comma’s properties. All of that appears to be unknown at this stage and may remain a mystery.
