Porcupine rank three family: Difference between revisions

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 porcupine rank-3 family of temperaments tempers out the porcupine comma or maximal diesis, 250/243. If nothing else is tempered out we have a 7-limit planar temperament, with an 11-limit comma we get an 11-limit temperament, and so forth.

Rank-3 porcupine

Subgroup: 2.3.5.7

Comma list: 250/243

Mapping: [⟨1 2 3 0], ⟨0 -3 -5 0], ⟨0 0 0 1]]

mapping generators: ~2, ~10/9, ~7

Optimal tuning (POTE): ~2 = 1\1, ~10/9 = 163.9504, ~7/4 = 970.0552

Optimal ET sequence: 7d, 8d, 14c, 15, 22, 37, 51, 73c

Badness: 0.535 × 10^-3

Sonic

Subgroup: 2.3.5.7.11

Comma list: 55/54, 100/99

Mapping: [⟨1 2 3 0 4], ⟨0 -3 -5 0 -4], ⟨0 0 0 1 0]]

Optimal tuning (POTE): ~2 = 1\1, ~11/10 = 164.0777, ~7/4 = 967.8413

Optimal ET sequence: 7d, 8d, 14c, 15, 22, 37, 51, 88b

Badness: 0.523 × 10^-3
