Diminished, 12 & 16, is a 5-limit temperament with period 1\4 (representing 6/5) and generator 3/2 (or 25/24); it is associated with tetrawood (4L 4s), called the diminished scale in conventional music theory. It tempers out 648/625, the difference between four 6/5 minor thirds and the octave.

Many tuning optimization algorithms rate diminished as optimal near 12edo. However, you might want a better 5/4, and if you do, you have to flatten the 3/2 generator (as in 28edo or 40edo).
