25/21, the quasi-tempered minor third, is the interval between [[6_5|6/5]] and [[10_7|10/7]], and also [[7_5|7/5]] and [[5_3|5/3]]. It is 126/125 flat of 6/5, and tempering 126/125 out makes the 1-6/5-10/7 triad into a diminished triad where two minor thirds make up a [[tritone]]. It is extremely close to 3 steps of [[12edo]] (300 cents).</pre></div>
