Oops, a typo here: If p denotes the lowering koron and < the raising sori, one 
has < = #p (sharp koron) and p = b> (flat sori). So if the sori is set to raise 
with two syntonic commas, then the koron is a flat raised by two syntonic 
commas. This corresponds Hormoz Farhat neutral second n set to a Pythagorean 
minor second m raised by two syntonic commas.

So in particular, Sabat's triple arrow accidentals would not be needed. In 
Persian music, one only uses those with two arrows up. Those with two arrows 
down do not occur.

One can see this in the regularE53.ly file I wrote: the Persian accidentals are 
those with “uu”, not using those with “dd”. Turkish accidentals use both “u” 
and “d”.
