496 equal divisions of the octave (496edo), or 496-tone equal temperament (496tet), 496 equal temperament (496et) when viewed from a regular temperament perspective, is the tuning system that divides the octave into 496 equal parts of about 2.42 ¢ each.
Theory
496edo is strongly related to the 248edo, but the patent vals differ on the mapping for 13. As such, in the 11-limit it supports a compound of two chains of 11-limit bischismic temperaments. In the 13-limit patent val, first step where 496edo is not contorted, it tempers out 4225/4224.
496edo is good with the 2.3.11.19 subgroup, for low-complexity just intonation. Higher limits that it appreciates are 31, 37, and 47. In the 2.3.11.19 subgroup, 496edo tempers out 131072/131043.
496 is the 3rd perfect number, and its divisors are 1, 2, 4, 8, 16, 31, 62, 124, 248, the most notable being 31.
