512/507, the tridecimal neutral thirds comma, is a 13-limit (also 2.3.13 subgroup) comma with a value of roughly 17.0 cents. It is significant in just intonation as the amount by which the tridecimal neutral third, 16/13, differs from its fifth complement, 39/32, as well as the amount by which a stack of two 1053/1024 quartertones fall short of the apotome.
Tempering out this interval equates both tridecimal neutral thirds to the true neutral third sqrt(3/2), and can be called harmoneutral temperament, as it tempers the harmonic neutral third together with its fifth complement.
