-The '''Alpharabian tuning''' is an [[11-limit]] version of [[just intonation]]—specifically the version that is limited to the '''2.3.11 [[subgroup]]'''—that is currently being pioneered in large part by [[User:Aura|Aura]], with significant parts of this research having been made almost two years earlier by [[User:Spt3125|Spt3125]].
+The '''2.3.11 subgroup''' (AKA ''ila'' in [[color notation]], or '''Alpharabian tuning''') is a [[just intonation subgroup]] consisting of [[Rational interval|rational intervals]] where [[2/1|2]], [[3/1|3]], [[11/1|11]] are the only allowable [[Prime factor|prime factors]], so that every such interval may be written as a ratio of integers which are products of 2, 3 and 13; this makes it a rank-2 system.
+It is currently being pioneered in large part by [[User:Aura|Aura]], with significant parts of this research having been made almost two years earlier by [[User:Spt3125|Spt3125]].
