Theory

451 = 11 × 41, and 451edo shares its fifth with 41edo. Unlike 41, however, 451 is only consistent to the 7-odd-limit, though it has a reasonable approximation up to the 13-limit using the patent val. The equal temperament tempers out 390625000/387420489 (quartonic comma) in the 5-limit; 2401/2400, 65625/65536, 703125/702464, 2100875/2097152, in the 7-limit; 6250/6237, 42592/42525, 42875/42768, 43923/43904 in the 11-limit; and 625/624, 2080/2079, 2200/2197, 4096/4095, 4225/4224, 4459/4455, and 17303/17280 in the 13-limit. It supports tertiaseptal, tertiseptisix, and hemermacomp, providing the optimal patent val for 5-limit quartonic.

Subsets and supersets

Since 451 factors into 11 × 41, 451edo has 11edo and 41edo as its subsets.
