[[94edo]] is a "wheel" for some [[fractional-octave temperaments]] because of its excellent [[3/2|perfect fifth]].  
[[94edo]] is a "wheel" for some [[fractional-octave temperaments]] because of its excellent [[3/2|perfect fifth]], which is a semiconvergent. Hence a natural option is to temper out the [[94-comma]] while leaving other generators as independent.
 
Not only 94edo is notable for its semiconvergent [[3/2|perfect fifth]], it is also the first ET [[consistent]] in the [[23-odd-limit]]. On top of that, [[282edo]], which is 94 × 3, is also consistent equally as far (on top of being the first distinctly consistent in it), thus providing natural octave-merger option.
 
Hence considered below is garistearn.

The garistearn temperament (94 & 282) tempers out the same commas as [[94edo]] in the [[2.3.7 subgroup]] while adding an independent generator for [[prime interval|prime]] [[5/1|5]].  
Named by [[Xenllium]] in 2021, the garistearn temperament (94 & 282) tempers out the same commas as [[94edo]] in the [[2.3.7 subgroup]] while adding an independent generator for [[prime interval|prime]] [[5/1|5]].
