→Tricot or Quadsatriyo family (P8, P12/3): corrected the pergen to P11/3, replaced 13-limit ratios with 5-limit ones (since the defining comma is 5-limit), linked to relevant 7-limit and 13-limit clans, added 5/4's mapping. |

This low-accuracy family of temperaments tempers out the laconic comma, {{Monzo|-4 7 -3}} (2187/2000), which is the difference between three 10/9's and one 3/2. The generator is ~10/9 = ~230¢. 5/4 is equated to 7 generators minus 1 octave. Laconic is supported by [[16edo]], [[21edo]], and [[37edo]] (using the 37b mapping), among others. An obvious 7-limit interpretation of the generator is ~8/7, which leads to Gamelismic aka Latrizo. | This low-accuracy family of temperaments tempers out the laconic comma, {{Monzo|-4 7 -3}} (2187/2000), which is the difference between three 10/9's and one 3/2.

The generator is ~59049/40960 = [-13 10 -1> = 633¢, or its octave inverse ~81920/59049 = 567¢. Three of the latter generators equals a compound 4th of ~8/3. 5/4 is equated to 14 octaves minus 29 of these generators. An obvious 7-limit interpretation of the generator is 81/56 = 639¢, a much simpler ratio which leads to the [[Tour of Regular Temperaments#Latriru clan (P8, P11/3)|Latriru clan]]. An obvious 13-limit interpretation is 13/9 = 637¢, an even simpler ratio implying the [[Tour of Regular Temperaments#Satritho clan (P8, P11/3)|Satritho clan]]. | ||
