"In all the metres, keep all disyllabic letters in the first (expansion). Keep a monosyllyabic letter below the first (available) disyllabic letter (and) write the remaining letters (on the right of the replaced letter) as they are and complete (the metre) by disyllabic letters (on the left of the replaced letter). Follow the process repeatedly till all the letters become monosyllabic."10
Variations of the metres having 1, 2 and 3 letters are as given below. 1 letter 2 letters
3 letters SS

Indian authorities on metrical sciences have treated two types of construction problems of combinatorics in metric. These are the nasta analysis and the uddista analysis. Aim of the former is to find the unknown (naşta) structure of a particular variaticn of a given metre, the serial number of this variation amidst all variations of the metre being given.
Ācārya Jayadeva's rule for finding the nașța may be translated as given below.
“If the serial number be an even one, it is halved and a monosyllabic letter is obtained. If it is an odd one, unity is added to it and then (he result is) halved and a disyllabic letter is obtained. The process is continued till (such number of letters as are equal to) the number of letters in the metre, are obtained."11
Let us find the 11th variation of the metre having 4 letters. Since 11 is odd so 1 is added to it and the sum is halved. Thus, 6 is obtained
