'''243/242''', otherwise known as the '''rastma''', is an [[11-limit]] comma with a value of roughly 7.13912 [[cent|cents]].  It is significant in Just Intonation as the amount by which a stack of two [[33/32]] quartertones fall short of an [[2187/2048|apotome]] as well as the difference between [[243/128]] and [[121/64]].  Tempering it out leads to a form of '''rastmic temperament'''.  When not tempered out, the rastma behaves much as the 11-limit counterpart to the 5-limit's [[81/80|syntonic comma]]- a property that becomes especially apparent when one works extensively with 33/32 quartertones.
