-The '''fidesma''', with a ratio of '''2025/2023''' (also 3.5.7.17 [[subgroup]]) is the difference between two [[17/15]] wide whole tones and a [[9/7]] supermajor third. Measuring about 1.7{{cent}}, it is an [[unnoticeable comma]]. It is the [[superpyth]] counterpart of [[1445/1444]], tempered out in any scale where the 5th is sharp enough that two of them approximates 17/15 and four 9/7, most notably [[22edo]], which is very close to quarter comma superpyth.

-It factors into two superparticular intervals: [[1701/1700]] × [[2500/2499]].
+It factors into [[1701/1700]] × [[2500/2499]] (and, of course, [[2024/2023]] × [[2025/2024]]), extending fidic temperament to the 2.3.5.7.11.17(.23) subgroup. No music is known to have been composed in this temperament to date, but it may receive some attention while the year number of the [[Wikipedia:Gregorian calendar|Gregorian calendar]] progresses to 2025.
