The 193 equal divisions of the octave (193edo), or the 193(-tone) equal temperament (193tet, 193et) when viewed from a regular temperament perspective, is the equal division of the octave into 193 parts of about 6.22 cents each.
Theory
193edo provides the optimal patent val for the sqrtphi temperament in the 13-, 17- and 19-limits, and for the 13-limit minos and vish temperaments. It is the 44th prime edo.
