The temperament generated by tempering out the frameshift comma.

It still needs to be decided whether this name refers to the higher-rank 11-limit tuning implied by the comma, or whether this name applies to the the rank-2 2.3.11 subgroup tuning implied by the comma.

Whichever it is, the other temperament will have to be given another name that relates to frameshift in some way.
