254803968/244140625, the hypovishnuzma, is a 5-limit comma, which represents the difference between a stack of six classic chromatic semitones (25/24) and a perfect fourth (4/3). This comma is larger than 25/24 itself. If one more 25/24 is subtracted from the hypovishnuzma, we get the vishnuzma.
Notable edos that temper the hypovishnuzma include 15, 28, 43, 58, 73, 101. These are the only edos that temper out this comma whose patent vals are unenfactored. Although 129edo inherits its patent val from 43edo (thus enfactored), 129p is the last val to temper out hypovishnuzma, and curiously, also the last val to temper out 81/80, the syntonic comma.
