The 342 equal divisions of the octave (342edo), or the 342(-tone) equal temperament (342tet, 342et) when viewed from a regular temperament perspective, is the equal division of the octave into 342 parts of 3.50877 cents each.
Theory
342edo is a very strong 11-limit system; not until 1848 do we reach one with a lower 11-limit relative error. It is, as one would expect, distinctly consistent through the 11-odd-limit, but goes no higher; nonetheless, it is a zeta peak edo. A basis for the 11-limit commas is 2401/2400, 3025/3024, 4375/4374 and 32805/32768. It is the optimal patent val for 11-limit hemitert temperament, and supports hemiennealimmal.
342 factors as 2 × 32 × 19, with subset edos 2, 3, 6, 9, 18, 19, 38, 57, 114, and 171.
