The 7-39-comma (monzo: 2.3.13 [37 -7 -7⟩, ratio: 137 438 953 472 / 137 231 006 679) is a unnoticeable 13-limit comma of about 2.62 cents. It is the amount by which a stack of seven 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 Shasavistic theory, it is called Safusagnama.
It factors into 816293376/815730721 and the tridecapyth comma, and is also equal to seven minismas minus the akjaysma. Thus, tempering out any of those pairs of commas implies also tempering this out.
