# 270edo

The 270 equal division divides the octave into 270 equal parts of 4.4444 cents each. It is a very strong 13-limit system, distinct and consistent through the 15 odd limit, and is the thirteenth zeta integral edo. In the 5-limit it tempers out the ennealimma, |1 -27 18>, the vulture comma, |24 -21 4>, and the vishnuzma or semisuper comma, |23 6 -14>. In the 7-limit it tempers out 2401/2400 and 4375/4374, so that it supports ennealimmal temperament, the wizma, 420175/419904 and the landscape comma, 250047/250000. In the 11-limit, it tempers out 5632/5625, 3025/3024 and 9801/9800. Finally in the 13-limit it tempers out 676/675, 1001/1000, 1716/1715 and 2080/2079, making it an archipelago tuning, and the optimal patent val for some of the archipelago temperaments.
