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.
The concoctic scale for 298edo is a scale produced by a generator of 105 steps (paraconcoctic), and the associated rank two temperament is 105 & 298.
