The tridecatonic temperament (26 &amp; 39) has a period of 1/13 octave. It tempers out the tridecalimma, {{monzo| -11 26 -13 }} in the 5-limit. There are some extensions for 7-limit, including tridecatonic (26 &amp; 39d, tempering out 4000/3969), [[Ragismic microtemperaments #Trideci|trideci]] (26 &amp; 39, tempering out 4375/4374), and [[26th-octave temperaments|bosonic]] (26 &amp; 130, tempering out 321489/320000).
