257298363/256000000, the historisma, is a 7-limit comma that is the difference between a stack of six septimal chromatic semitones (21/20) and a perfect fourth (4/3). Tempering it out leads to the 7-limit version of the History temperament.

The hypovishnuzma, the difference between six classic chromatic semitones (25/24) and 4/3, can be considered the historisma's 5-limit counterpart. 43edo tempers out both, as it tempers out 126/125, which equates 21/20 and 25/24.
