The guerrisma, 1815/1792, is an 11-limit comma that is much like the larger inverse of the absinthma, from which it differs by the Alpharabian comma.
While the absinthma causes 11/8 to fall exactly halfway between 4/3 and 10/7, the guerrisma causes it to fall halfway between 4/3 and 7/5. It is also extremely close to 81/80, exceeding it only by a lehmerisma (3025/3024).
It is tempered out in such notable EDOs as 22, 31 and 53, as well as the still fairly significant 26 and 29, as well as in a whole panoply of rank-2 temperaments.
The name of this comma is derived from guerre, French for war, after the ratio of 1815/1792. 1792-1815 was a period of many wars involving France, including both the Revolutionary Wars and the Napoleonic Wars.
