सटीको वृत्तजातिसमुच्चयः [INTRODUCTION müla (vv. 37-38) or prathamasthāḥ varnāḥ in v. 36. The mūla of a Gāthā for example is 30 as we know from the Sālmali Prastāra. The figure that is thus obtained by deduction and addition as directed above is the required number. In the same way, when the number of letters in a particular permutation is given and its serial number in the midst of the permutations of the Mātrā Vștta is wanted, we should add 1 to this number and deduct the mūla from it. The resulting figure is the serial number that is wanted. Thus if the number of letters in the 5th variety of a Gāthā is asked, remove 1 from 5, which is its serial number, and add 30 to this which is the mūla of a Gāthā; we get 34 which represents the number of letters that was required. On the other hand, if the number of letters in a Gāthā is known (uddista), we can ascertain its position in the midst of its Prastāra, by the opposite process. Thus add 1 to this number (of letters) and deduct the mūla from it; so if the number of letters is given as 36, add 1 to it and deduct müla, i.e., 30, from the same. The resulting figure namely 7 is its serial number in the Prastāra (vv. 37-38).
14. Vv. 39-40 teach further how to find out the unknown (naşta) structure of a Gāthā and the like, when its serial number in the midst of its Prastāra is given, as also the unknown serial number of a Gāthā and the like whose structure is actually given (uddista). V. 39 teaches the latter and v. 40 the former. The commentator illustrates the process of Uddista from v. 39 itself. It is this :-First of all let the figure representing the possible number of the permutations of a Caturmātra or an Amśa be put under each of the 16 Amśas of the Gāthā (see p. 95). Thus under an odd Amśa put the figure 4, since out of the five possible permutations of a Caturmātra, one namely the Narendra (ISI) is not permitted here according to I. 23 above; similarly under each even Amsa where a Caturmātra is employed, put the figure 5 since all the five permutations can be employed here. Under the 6th Amśa put the figure ? since here only two permutations namely a Narendra (ISI) and a Vipra (IIII) are allowed, according to IV. 1 above, which also lays down that only a short letter shall be employed at the 14th Amśa (the 6th in the second half) and only a long letter is permitted at the 8th and the 16th Ambas. So that put 1 under the 14th and also under the 8th and the 16th Amśas. Then multiply the figure under the last Amśa, i.e., the 16th, by that under its predecessor, i.e., the 15th Assa, and deduct from the multiplication a figure which represents the seșa, that is, the permutaLions that are left out by the one which is actually employed at the preceding Amśa. Thus multiply 1 by 4 and deduct 1 which in the particular
