'''137438953472/137231006679''' is a 13-limit [[unnoticeable comma]] of about 2.62{{cent}}. It is the amount by which a stack of 7 [[39/32]]'s fall short of two octaves. It is tempered out in low edos that are a multiple of 7, which approximate 39/32 within a fraction of a cent. In [[L4MPLIGHT#Shasavistic music theory|Shasavistic theory]], it is called ''Safusagnama''.

It factors into [[816293376/815730721]] and the [[tridecapyth comma]], and is also equal to seven [[minisma]]s minus the [[akjaysma]]. Thus, tempering out any of those pairs of commas implies also tempering this out.
