2777edo is [[consistent]] to the [[7-odd-limit]] and its [[harmonic]] [[3/1|3]] is about halfway its steps. Using the 2.9.5.7.11.13.17.23.29.31 [[subgroup]], it [[tempering out|tempers out]] [[12376/12375]], [[14400/14399]], [[25025/25024]], [[123201/123200]], 20736/20735, [[194481/194480]], 16445/16443, 27625/27621 and 23716/23715. Using the no-3-or-19 23-limit subgroup, it tempers out [[25025/25024]].
