Olympic clan
The olympic clan of rank-3 temperaments tempers out the olympia, 131072/130977 = [17 -5 0 -2 -1⟩. This has the effect of equating the undecimal quartertone (33/32) with a stack of two septimal commas (64/63).
For the rank-4 olympic temperament, see Rank-4 temperament #Olympic (131072/130977).

Overview to extensions
The second comma in the comma list determines how we extend olympian to include the harmonic 5. Akea adds 385/384, and finds the harmonic 5 by equating the syntonic comma (81/80) with the septimal comma. Orthoschismic adds 32805/32768, and finds the harmonic 5 on the chain of fifths. Cassaschismic adds 19712/19683 with an independent generator for harmonic 5. Pessoal adds 9801/9800, splitting the octave into two. Lif adds 2401/2400, splitting the perfect fifth into two. Baffin adds 5632/5625, splitting the perfect twelfth into two. Lux adds 3025/3024, splitting the ~21/16 into two. Hera adds 6144/6125 or 8019/8000, splitting the ~21/16 into three. Finally, sophia adds 42875/42768, splitting the ~8/7 into three. These all have neat extensions to the 13-limit via tempering out both 2080/2079 and 4096/4095.
Temperaments discussed elsewhere are:
- Akea (+385/384) → Hemifamity family
- Pessoal (+9801/9800) → Kalismic temperaments
- Lif (+2401/2400) → Breed family
- Lux (+3025/3024) → Lehmerismic temperaments
- Hera (+6144/6125) → Porwell family
Considered below are orthoschismic, cassaschismic, baffin and sophia.
