While not highly accurate for its size, 229edo is the point where a few important temperaments meet, and is [[consistency|distinctly consistent]] in the [[11-odd-limit]]. It [[tempering out|tempers out]] 393216/390625 ([[würschmidt comma]]) and {{monzo| 39 -29 3 }} ([[alphatricot comma]]) in the [[5-limit]]; [[2401/2400]], [[3136/3125]], [[6144/6125]], and [[14348907/14336000]] in the [[7-limit]]; [[3025/3024]], [[3388/3375]], [[8019/8000]], [[14641/14580]] and 15488/15435 in the [[11-limit]], notably [[support]]ing [[hemiwürschmidt]], [[newt]], and [[alphatrident]].  
The revision contents are below, presented both in the original Wikispaces Wikitext format, and in HTML exactly as Wikispaces rendered it.<br>
 
<h4>Original Wikitext content:</h4>
It extends less well to the 13-limit. Using the [[patent val]] {{val| 229 363 532 643 792 '''847''' }}, it tempers out [[351/350]], [[1573/1568]], [[2080/2079]], and [[4096/4095]]. Using the alternative 229f val {{val| 229 363 532 643 792 '''848''' }}, it tempers out [[352/351]], [[729/728]], [[1001/1000]], and [[1716/1715]].  
<div style="width:100%; max-height:400pt; overflow:auto; background-color:#f8f9fa; border: 1px solid #eaecf0; padding:0em"><pre style="margin:0px;border:none;background:none;word-wrap:break-word;white-space: pre-wrap ! important" class="old-revision-html">The //229 equal division// divides the octave into 229 equal parts of 5.240 cents each. In the 5-limit it tempers out the wuerschmidt comma, 393216/390625, and in the 7-limit 3136/3125, 6144/6125 and 2401/2400, so that it supports wuerschmidt and hemiweurschmidt temperament. 229 is the 50th prime EDO.</pre></div>
 
<h4>Original HTML content:</h4>
Higher [[harmonic]]s like [[17/1|17]], [[19/1|19]], and [[23/1|23]] are well-approximated, so it shows great potential in the no-13 23-limit. It tempers out [[561/560]], [[1089/1088]], and [[1701/1700]] in the 17-limit; [[476/475]], [[1216/1215]], [[1445/1444]], and [[1540/1539]] in the 19-limit; and [[484/483]], [[576/575]] and [[736/735]] in the 23-limit.
<div style="width:100%; max-height:400pt; overflow:auto; background-color:#f8f9fa; border: 1px solid #eaecf0; padding:0em"><pre style="margin:0px;border:none;background:none;word-wrap:break-word;width:200%;white-space: pre-wrap ! important" class="old-revision-html">&lt;html&gt;&lt;head&gt;&lt;title&gt;229edo&lt;/title&gt;&lt;/head&gt;&lt;body&gt;The &lt;em&gt;229 equal division&lt;/em&gt; divides the octave into 229 equal parts of 5.240 cents each. In the 5-limit it tempers out the wuerschmidt comma, 393216/390625, and in the 7-limit 3136/3125, 6144/6125 and 2401/2400, so that it supports wuerschmidt and hemiweurschmidt temperament. 229 is the 50th prime EDO.&lt;/body&gt;&lt;/html&gt;</pre></div>
 
The 229b [[val]] supports a [[septimal meantone]] close to the [[CTE tuning]].
