These are generalisations of Gordon Wery's lucite23 scale into a regular temperament.

Triencata temperament

Described by Osmium in October 2025. Relatively high accuracy; tunes the 2.3.5.13.17 subgroup (so it's a type of no-7s temperament).

Lucite temperament

Described by Budjarn Lambeth in October 2025. Relatively low accuracy but includes the full 17-limit.

Using Sintel Temperament Finder's badness, it has a badness of: 3.052.
