The '''greater tendoneutralisma''' is a [[small comma]] of the 2.3.13 subgroup which is the amount by which a stack of eight [[16/13]]'s minus two [[octave]]s falls short of [[4/3]]; that is, it is equal to ([[16/3]])/([[16/13]])<sup>8</sup> and so equivalently also to ([[13/3]])/([[16/13]])<sup>7</sup>. Although the comma is similar in size to something like 81/80, it is quite accurate because the error can be split evenly over eight 16/13's, so that the pure-3's tuning (very close to [[53edo]]) has 13 off by only 2.78{{cent}}. A more accurate (lower damage) way of achieving the same (finding 3 by stacking 13's) is by tempering the [[lesser tendoneutralisma]]. Very importantly, both are distinct ways of mapping 2.3.13, so that you can't combine them unless you want to use the trivial tuning of [[10edo]], so that edos > 10 which have a good 13 will usually pick between one of these two mappings. | The '''greater tendoneutralisma''' is a [[small comma]] of the 2.3.13 subgroup which is the amount by which a stack of eight [[16/13]]'s minus two [[octave]]s falls short of [[4/3]]; that is, it is equal to ([[16/3]])/([[16/13]])<sup>8</sup> and so equivalently also to ([[13/3]])/([[16/13]])<sup>7</sup>.
