462 equal divisions of the octave (abbreviated 462edo or 462ed2), also called 462-tone equal temperament (462tet) or 462 equal temperament (462et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 462 equal parts of about 2.6 ¢ each. Each step represents a frequency ratio of 21/462, or the 462nd root of 2.
462edo is enfactored in the 3-limit and inconsistent to the 5-odd-limit. It can be considered for the 2.3.7.11.17 subgroup, tempering out 1089/1088, 34992/34969, 944163/941192 and 10323369/10307264.

Subsets and supersets
462 factors into 2 × 3 × 7 × 11, with subset edos 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, and 231. 1386edo, which triples it, gives a good correction to the harmonics 3 and 5.
