The ratwolfsma, 351/350, is a 13-limit no-11 comma measuring about 4.9 cents. It is the difference between 28/27 and 26/25, between 81/70 and 15/13, and between 35/27 and 13/10.

In terms of commas, it is 9801/9800 large of 364/363, and 4375/4374 small of 325/324, and it factors into (676/675)(729/728).

351/350 and 352/351, the minthma, are extremely close in size and make up a consecutive pair of 13-limit superparticular commas. Their difference is 123201/123200, the chalmersma, the smallest 13-limit superparticular comma; their sum is 176/175, the valinorsma, an 11-limit superparticular comma.

Tempering it out leads to the rank-five ratwolf temperament, enabling the ratwolf triad.
