351/343, the keladisma, is a no-twos 13-limit and 3.7.13 subgroup comma of about 40 cents. It can be defined as the difference between a stack of three 7/3 minor tenths and the 13th harmonic. Tempering this out in the 3.7.13 subgroup leads to the keladic temperament, generated by a sharp 7/3 or flat 9/7 against the tritave.
This comma is notably also tempered out in Minalzidar, the 3.7.11.13 extension of Mintaka, and in squad, a full 13-limit extension of squares.
