Unidec is the regular temperament defined in the 7-limit by tempering out 1029/1024, the gamelisma, and 4375/4374, the ragisma, with the 11-limit extension adding 385/384 or 441/440 to the comma list, featuring a period of a semioctave and a generator of a classic whole tone.

There are two viable 13-limit extensions: hendec and ekadash.

See Gamelismic clan #Unidec for technical details.
