This is an unlabelled set of pentatonic scales in rotation in what first appeared to be a process similar to that used in his Purvi papers but was not in the end. Adjacent pages carry the year 1982. This set of 5 limit scales he has mapped over 53 squares with the whole set comprising 17 different pitches. In 53 unit sizes would be 53232323-53232323-9 implying two tetrachordal like blocks of 4/3 repeated with a 9/8 disjunction. Each interval shift involve the difference of a 25/24. The paper deserves more more attention. Comments and observations are welcome on this one.
