'''206edo''' is the [[EDO|equal division of the octave]] into 206 parts of 5.8252 [[cent]]s each. It is closely related to [[103edo]], but the patent vals differ on the mapping for 3, 11, and 19.

206edo is closely related to [[103edo]], but the [[patent val]]s differ on the mapping for 3, 11, and 19.
