The rhyme scheme (1121 2231 2232 3341) is given by the binary weight (OEIS A000120 [2]) of the line numbers. Also known as the “Hamming weight,” this is the sum of the number’s binary digits. The OEIS entry has many interesting facts about this sequence. The respective rhymes are used (1 + 4, 6, 4, 1) times, and this relationship with ( n j ) generalizes if the form is extended to 2 lines. Coincidentally, Omar Khayyam was one of the pioneers of binomial coefficients: what is known in the West as “Pascal’s triangle” has been called the “Khayyam triangle” [1] in Iran!
