The linus comma (monzo[11 -10 -10 10) is a small 7-limit comma measuring about 5.57 ¢. It is the difference between a stack of 10 15/14's and the octave.

Temperaments

Tempering out this comma alone in the 7-limit results in the rank-3 linus temperament. Edos not divisible by 10 cannot temper it out. For technical details see Kalismic temperaments #Linus.

Etymology

The name linus was given by Gene Ward Smith in 2011, referring to the fact that it is a "line comma" since the simplest comma pump will simply march along a line of the tetrad lattice[1][2].

A 2016 article on this wiki by Mason Green, not aware of this comma already having been named, dubbed it the higherlovesma, and the corresponding rank-3 temperament winwood.
