242/225, the interval between 22/15 and 15/11, is about 126 cents in size and may be called doubly undecimal-diminished second: the amount by which the relating fourth is augmented (4/3*45/44=15/11) and the fifth is diminished (3/2*44/45=22/15) is applied twice to the classic major second (9/8*44/45*44/45=242/225).^{[clarification needed]}
