^{4}× 31**496 equal divisions of the octave** (abbreviated **496edo** or **496ed2**), also called **496-tone equal temperament** (**496tet**) or **496 equal temperament** (**496et**) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 496 equal parts of about 2.42 ¢ each. Each step represents a frequency ratio of 2^{1/496}, or the 496th root of 2.

496edo is enfactored in the 11-limit, with the same tuning as 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, it tempers out 4225/4224.

496edo is good with the 2.3.11.19 subgroup. For higher limits, it has good approximations of 31, 37, and 47. In the 2.3.11.19 subgroup, it tempers out 131072/131043.
