The comma 180224/177147 is an 11-limit (2.3.11 subgroup) comma that is the difference between 33/32 and the Pythagorean comma. This comma is tempered out in EDOs with fifths in the gentle region such as 17edo, 29edo, 46edo and 63edo, making 11/8 is a double-diminished fifth (C-Gbb), 11/9 is an augmented second (C-D#), and 27/22 is a diminished fourth (C-Fb). This allows for the access of undecimal intervals in certain modes of the 5L 7s chromatic scale but not the diatonic scale.
