Low-complexity just intonation
Low-complexity JI (or LCJI; "low JI" is discouraged) is a term for JI that is based on or generated by a restricted set of simple JI intervals (such as 3/2, 4/3, 5/4, 6/5, 7/4, 7/6, 9/8, 11/8, 13/8, 15/8). This term is used in opposition to primodality or other higher-harmonic series approaches such as nejis.
