'''1001edo''' divides the octave into parts of 1.(19880) cents each.
{{ED intro}}


== Theory ==
1001edo is in[[consistent]] to the [[5-odd-limit]] and [[harmonic]] [[3/1|3]] is about halfway between its steps. Otherwise, it has good approximations to harmonics [[7/1|7]], [[9/1|9]], [[11/1|11]], [[13/1|13]], [[19/1|19]], and [[23/1|23]], making it suitable for a 2.9.7.11.13.19.23 [[subgroup]] interpretation, with an optional addition of either [[5/1|5]], or [[15/1|15]]. In such a subgroup, it tempers out 14651/14641, 157757/157696, and 184877/184832.

1001 factorizes as 7 x 11 x 13, and therefore by extension it contains all these smaller EDOs. It's composite divisors are 77, 91, and 143.


The best prime subgroup for 1001edo is 2.7.11.13.19.23. In such a subgroup, it tempers out 14651/14641, 157757/157696, and 184877/184832. Taking the full 23-limit enables to determine that 1001edo tempers out 1288/1287, 2300/2299, 2737/2736, 2926/2925, and 5776/5775.  
Taking the full 23-limit enables to determine that 1001edo tempers out 1288/1287, 2300/2299, 2737/2736, 2926/2925, and 5776/5775. Using the 1001b val, that is putting the 3/2 fifth on the 585th step instead of the 586th, 1001edo tempers out 936/935, 1197/1196, and 1521/1520, as well as the [[parakleisma]].
