1ed97.5c
97.5cET is an equal-step tuning with steps of 97.5 cents (or each 13th step of 160edo). This system doesn't contain good approximations of fourth (4/3), fifths 3/2, octave 2/1, major ninth (nonet) 9/4, eleventh 8/3, and tritave 3/1 which makes it quite "atonal" and xenharmonic (but nevertheless harmonic in its way, see #Music).
