1793edo is naively consistent in the 2.3.5.11.13.17 subgroup, in which it has a comma basis 4225/4224, 6656/6655, 42500/42471, 4787200/4782969, 703125/702559. Higher prime harmonics it supports to <25% error are 23, 31, 41, 53, 61.

~~If a mapping for~~ 7 is ~~added~~, ~~this gives two interpretations~~. ~~First is the patent val~~, which has a comma basis ~~2080/2079, 3025/3024,~~ 4225/4224, ~~5832~~/~~5831~~, ~~14875~~/~~14872~~, ~~108086/108085. The 1793d val has a comma basis 1225~~/~~1224~~, ~~8624~~/~~8619~~, ~~12376/12375~~, ~~14400/14399~~, ~~42500/42471~~, ~~29755593/29744000.

1793edo is only [[consistent]] to the [[5-odd-limit]] since [[harmonic]] [[7/1|7]] is about halfway between its steps. Nonetheless, it is a good 2.3.5.11.13.17 [[subgroup]] system, in which it has a [[comma basis]] [[4225/4224]], [[6656/6655]], 42500/42471, 4787200/4782969, 703125/702559. Higher prime harmonics it supports to <25% error are 23, 31, 41, 53, 61.

~~1793edo tempers out~~ the [[~~jacobin~~ comma]], ~~which is quite thematic given that 1793 is another notable year of the French Revolution~~, ~~just as~~ [[~~1789edo|1789~~]] is. The comma basis for the ~~1789 & 1793~~ temperament ~~in the 2.5.11.13 subgroup is 6656/6655, {{monzo|-176 23 -2 35}}~~.

If a mapping for 7 is added, this gives two interpretations. First is the [[patent val]], which has a comma basis {[[2080/2079]], [[3025/3024]], 4225/4224, [[5832/5831]], 14875/14872, 108086/108085}. The 1793d val has a comma basis {[[1225/1224]], 8624/8619, [[12376/12375]], [[14400/14399]], 42500/42471, 29755593/29744000}. It provides the [[optimal patent val]] for the [[luminal]] temperament.
