The only notable low-harmonic-entropy scale for this MOS pattern is sensi, in which two generators make a 5/3. The harmonic entropy of sensi[5] is still fairly high relative to other pentatonic scales, such as meantone. It's also improper.

Names

The TAMNAMS system suggests the name antipentic, in opposition to pentic used for 2L 3s.
