298edo has excellent representation of the 2.5.11.17.23.43.53.59 subgroup, with all the harmonics having errors of less than 10 . It is a double of [[149edo]], but the patent vals differ on the mapping of the 7th, 11th, and 13th harmonics. Thus it can be viewed as a "spicy 149edo" as a result, and different temperaments can be extracted from 298edo by simply viewing its prime harmonics as variations from 149edo by its own half-step.   
298edo has excellent representation of the 2.5.11.17.23.43.53.59 subgroup, with all the harmonics having errors of less than 10 rc. It is a double of [[149edo]], which is the smallest edo that is uniquely consistent within the [[17-odd-limit]].. However, the patent vals differ on the mapping of 7, 11, and 13th harmonics. Thus it can be viewed as a "spicy 149edo" as a result, and different temperaments can be extracted from 298edo by simply viewing its prime harmonics as variations from 149edo by its own half-step.   


298edo supports unconventional extensions of [[Sensi]] to higher dimensions. The 298d val in 11-limit (149-edo with 298-edo 11/8) supports [[hagrid]], in addition to 118 & 31 & 298d variant of [[hemithirds]]. In the 298cd val, it supports [[miracle]].

The patent val in 298edo is desolate for temperaments, but it supports [[bison]] temperament and the rank 3 temperament hemiwuermity. In the 2.5.11.13 subgroup, 298edo supports [[emka]]. In the full 13-limit, 298edo supports an unnamed 77 & 298 temperament with [[13/8]] as its generator.

In the 2.5.11.17.23.43.53.59, 298edo tempers out 3176/3175, 3128/3125, 3128/3127, 32906/32065 and 76585/76582.
