It is the second smallest equal temperament (after [[29edo]]) whose perfect fifth is closer to just intonation than that of 12-ET, and is the seventh [[http://www.research.att.com/%7Enjas/sequences/A117538|Zeta integral tuning]] after 31. The latter has to do with the fact that it can deal with the 11-limit fairly well, and the 13-limit perhaps close enough for government work, though its 13/10 is 14 cents sharp.

&lt;br /&gt;

  Taking every third degree of 41edo produces a scale extremely close to &lt;a class="wiki_link" href="/88cET"&gt;88cET&lt;/a&gt; or 88-cent equal temperament (or the 8th root of 3:2). Likewise, taking every fifth degree produces a scale very close to the equal-tempered &lt;span class="wiki_link_new"&gt;&lt;a class="wiki_link" href="/BP"&gt;Bohlen-Pierce&lt;/a&gt;&lt;/span&gt;&lt;a class="wiki_link" href="/BP"&gt; Scale&lt;/a&gt; (or the 13th root of 3).
