Neutral temperaments
From Xenharmonic Reference
Dichotic is an exotemperament that can be defined to temper out 25/24, the dicot comma, 45/44, and 64/63. As a result it also tempers out 55/54.
Interval chart
This interval chart uses Partch's 11-limit tonality diamond and maps it onto 7edo and 10edo. This also gives an idea of what intervals are possible in dichotic temperament. Intervals in bold are in the 7-note MOS (symmetric mode) and intervals in italics are in the 10-note MOS (both near-symmetric modes). Note that the interval that can be mapped to 11/8 and 10/7 and the interval mapped to 7/5 and 16/11 cannot coexist in the same 10-note MOS.
