The Sinarabian comma is an 13-limit (also 2.3.11.13 subgroup) unnoticeable comma with a ratio of 85293/85184 and a value of approximately 2 cents. This comma is identifiable as the amount by which a stack of two 88/81 artoneutral seconds falls short of a 13/11 Neo-Gothic minor third, and also the amount by which a stack of three 11/9 artoneutral thirds fall short of 117/64, and even the comma that separates 1053/1024 and 1331/1296. In terms of comma relations, it separates 243/242 from 352/351, separates 144/143 from a stack of two instances of 243/242, and, is the sum of the frameshift comma and the tridecapyth comma. The name of this comma comes from a portmanteau of "Ibn Sina" and "Alpharabian", and was given by Aura on the basis of a series of connections between intervals that he found and shared with Margo Schulter, who took note of a variety of implications, the details of which will be added to this article later.
