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.

This is a collection of rank-2 temperaments that temper out the orwellisma (monzo: [6 3 -1 -3⟩, ratio: 1728/1715).

Temperaments discussed elsewhere are:

Considered below are secant, infraorwell, quartonic, sentinel, diesic, philips, triskaidekic, and pentaorwell.
