1L 6s or antiarcheotonic is the MOS pattern Lssssss with small steps ranging from 0\1 (0¢) to 1\7 (one step of 7edo = 171.4¢).

There is one notable low-harmonic-entropy scale with this MOS pattern: porcupine, in which two generators make a 6/5 and three make a 4/3.

Other scales include very improper (incomplete) versions of negri, 12edo, etc.
