Quindromeda family
The quindromeda family tempers out [56 -28 -5⟩, equating the Pythagorean comma with a stack of five schismas, making it a member of the schismic-Pythagorean equivalence continuum.
Quindromeda
The name quindromeda comes from "quintans" (Latin for "one fifth") and "Andromeda", because the generator is 1/5 of the andromeda fourth (~4/3, about 497.6 cents).

Subgroup temperament
The quindromeda temperament works well for the 2.3.5.17.19 subgroup, tempering out the password comma (1216/1215), aureusma (1445/1444), and 6144/6137. An obvious 17-limit interpretation of the generator is ~18/17, equating three 18/17s with 19/16, five 18/17s with 4/3, and twenty-eight 18/17s with the fifth harmonic.

Quintagar
The quintagar temperament (12&217) tempers out the hemimean comma (3136/3125) and the garischisma (33554432/33480783) in the 7-limit. In the 2.3.5.7.17.19 subgroup, 256/255 (the difference between 16/15 and 17/16), 289/288 (between 17/16 and 18/17), 324/323 (between 18/17 and 19/18), 361/360 (between 19/18 and 20/19), and 400/399 (between 20/19 and 21/20) are equated together, and 476/475 (between 28/25 and 19/17) is tempered out. Immediate 2.3.5.7.11.17.19 extensions include quintoneum (12&217, tempering out 441/440), quinsandra (217&229, equating 385/384 with 400/399), and quinsandric (12&229, equating 400/399 with 441/440). Full 19-limit extensions include quintoneum (12f&217), quintoneoid (12&217), quinsandra (217&229), quinsandric (12f&229), and quinsandro (12&229). The name quintagar is so named because the generator is 1/5 of the garibaldi fourth (~4/3, about 497.8 cents).
