The 1171 equal divisions of the octave (1171edo) divides the octave into 1171 parts of size 1.0248 cents each. It is a very strong 5-limit division, being the first one past 612 with a lower 5-limit relative error. It has a 5-limit comma basis consisting of the monzisma, [54 -37 2⟩ and whoosh, [37 25 -33⟩. While not a strong higher-limit system, it is uniquely consistent through the 27-odd-limit, and is very strong on the 2.3.5.11 subgroup. We might also note that 1171 is a prime number.
