1L 4s is a moment of symmetry scale consisting of 1 large step and 4 small steps, repeating every octave. This scale is made using a generator ranging from 960¢ to 1200¢, or from 0¢ to 240¢.
The only notable low-harmonic-entropy scale for this MOS pattern is slendric or gamelismic, in which the generator is 8/7 and three of them make a 3/2. Other scales include very improper (incomplete) versions of porcupine, negri, etc.
