2L 1s is a trivial 3-tone scale. 2L 1s is one of two halves in the tree of strict MOSes, the other being 1L 2s. 2L 1s is the parent MOS of the pentic scale 2L 3s, which is itself the parent of the diatonic and antidiatonic scales, as well as the antipentic scale 3L 2s, which is itself the parent of the oneirotonic and checkertonic scales.
