This is a list of 12-tone NEJIs designed by me. The goal is to make a scale that satisfy the restrictions below:

• All fifths are acceptable (≤8 cents off from just).
• The least common denominator is small enough (≤256).
• Most notes are in a manageable prime limit.
• It contains some simple just intervals.

Fifths

Assuming G centered:

• One fifth flatten by 243/242 (~7.139 cents) at B-F♯
• Two fifths flatten by approximately half of 153/152 (~5.7 cents each) at G♯-D♯-A♯
• One fifth flatten by 513/512 (~3.3 cents) at F-C
• One fifth flatten by 1089/1088 (~1.6 cents) at F♯-C♯
• Seven pure fifths at C-G-D-A-E-B, C♯-G♯ and A♯-F
