This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

The garischismic family of rank-3 temperaments tempers out the garischisma (ratio: 33554432/33480783, monzo[25 -14 0 -1). The head of this family is garischismic, which is generated by a perfect fifth and an independent generator for 5/4. Two apotomes i.e. 14 fifths octave-reduced make a septimal major second (8/7). Equivalently stated, the harmonic seventh (7/4) is found at the double-diminished octave (C–Cbb).

The best extension to the 11-limit identifies the 11/8 at +23 fifths. This is also the mapping used in cassandra, so we call it cassaschismic. An alternative, supported by andromeda, is androschismic.
