Diploid tricot is a temperament archetype with a half-octave period, and a generator that is a third of the size of a perfect fifth (233.98 ¢).
Diploid tricot temperaments usually generate the 4L 2s, 6L 4s, and 10L 6s MOS structures.
Intervals and notation
Diploid tricot notation is complicated as it conventionally requires either the introduction of new "hemipythagorean" ordinals or the use of scales other than the standard diatonic scale. Note and interval names are provided where diploid dicot intervals align with standard monocot intervals (which use chain-of-fifths notation).

Temperament interpretations
Here, there is one obvious temperament, baladic, which is useful for the 2.3.7.13.17 subgroup. It tempers out 169/168, which splits 7/6 in half (13/12~14/13) and one finds that the octave is therefore split in half via the interval 91/64, which is then equated to 17/12.
