590 equal divisions of the octave (abbreviated 590edo or 590ed2), also called 590-tone equal temperament (590tet) or 590 equal temperament (590et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 590 equal parts of about 2.03 ¢ each. Each step represents a frequency ratio of 21/590, or the 590th root of 2.
590edo has the same tuning as the 118edo in the 5-limit and provides a good correction for the harmonics 7, 11, and 13, altogether being consistent in the 15-odd-limit. Among the 118th-octave temperaments, it by definition tunes parakleischis as well as peithoian in the 590ee val.
Besides that, it is a tuning for the quintaschis temperament in the 7-limit.
