891/512, the Alpharabian ultramajor sixth, is the basic ultramajor sixth in the 2.3.11 subgroup. It differs from 7/4 by the pentacircle comma, and differs from 512/297 by the Betarabian comma. As suggested by its name, it is reached by tacking a 33/32 quartertone onto 27/16.
Among the more reasonably-sized large EDOs that represent this interval and other intervals in its class- such as 297/256, 2673/2048 and 8019/4096- with a pretty good level of accuracy include 159edo.
