'''7777/7776''', the '''pulsar comma''' or '''power of six repdigit comma''' is an unnoticeable comma of 0.223 cents, and it is a part of 101-limit [[just intonation]].

'''7777/7776''', the '''pulsar comma''' or '''power-of-six repdigit comma''' is an unnoticeable comma of 0.223 cents, and it is a part of 101-limit [[just intonation]].

The comma derives from the resemblance of a perfect power of 6, 7776, to a decimal repdigit number 7777. It is the difference between a stack of five [[6/1]]'s and 7, 11, and 101 harmonics stacked, or when octave-reduced, between 7/4, 11/8, and 101/64 and the Pythagorean major seventh, [[243/128]]. It is also the difference between 404/243 and 128/77.

The name origin is the following: power of six repdigit – ''psr'', which is the astronomical shortening for pulsars.

The name origin is the following: power-of-six repdigit – ''psr'', which is the astronomical shortening for pulsars.
