'''77/72''', the '''undecimal secor''', is between the 3\31 [[secor|secor]] of [[31edo]] and the 10\103 secor of [[103edo]]. It is 385/384 (4.5 cents) sharper than [[16/15]] and 540/539 (3.2 cents) flatter than [[15/14]]. In 11-limit JI scales it often appears, being the interval between [[12/11]] and [[7/6]], [[8/7]] and [[11/9]], [[9/7]] and [[11/8]], and their inversions. Tempering out 385/384 equates it with [[16/15]], tempering out 540/539 equates it with [[15/14]], and tempering out both makes it the marvel secor.
