Porcusmine

Porcusmine is a max-variety-3, generator-offset scale with step pattern 4L 3M 1s. It is equivalent to the porcupine (7L 1s) mos with 4 of the large steps made bigger and the other 3 made smaller, or to the smitonic (4L 3s) with an extra-small step added. Porcusmine is not chiral. 19edo is the smallest edo to support a non-degenerate porcusmine.

Porcusmine can be tuned as a 5-limit JI scale or a tempered version thereof, where L represents 10/9, M represents 27/25, and s represents 25/24.

"Porcusmine" is a name given by cellularAutomaton, who discovered it as a detempering of porcupine, although the scale has also been discussed by Kite Giedraitis and possibly others. The name is a portmanteau of "porcupine" and "smitonic", since its step sizes are intermediate between those of the 8-note porcupine and 7-note smitonic mosses.
