सटीको वृत्तजातिसमुच्चयः
[INTRODUCTION
shall contain 16 letters as explained above. When the Patākā Prastāra is thus completed, we should begin to read it in horizontal lines and we shall get all the different permutations of a metre as regards their structure of short and long letters. The serial number of each permutation also thus becomes fixed.

10. The fourth or the Samudra Prastāra is in form exactly like the Patākā and is intended for the same purpose. But the process by which it is done is different. Here the Prastāra is arranged in horizontal lines and not in vertical ones. In the first line put down as many long letters as there are letters in a Pāda of a given metre. Then, in the second line, place a short letter under the first long letter in the upper line and then copy out the other letters as they are in the upper line. Follow the same process in the subsequent lines until we get all short letters in the iast line. Only, when there are short letters preceding the first long letter in the upper line, we should write all long letters under all these in the lower line. Both these Prastāras serve the same purpose, namely, showing the structure of the different permutations of a metre. This same method is to be followed for doing the Prastara of Mātrā Vṛttas, but where by following the process the required number of Mātrās is not obtained in a particular Gaṇa, one short letter should be added in the beginning of that Gana and thus the required number should be completed. This extra short letter or Mātrā is to be disregarded in the process, i.e., no long letter is to be written under it in the next lower line. Only, in the case of the odd Gaņas of a Gāthā this extra short letter is to be placed under the last long letter of the Gana in the upper line and not at the beginning, as said above, thus avoiding the Narendra group (ISI) which is forbidden for these Ganas. Again in the case of the Ganas containing an odd number of Mātrās, i.e., 5, 7 etc., the first permutation should have the first letter short and the rest long ones. The fifth or the Viparita Samudra is just the opposite of this. In it the process of the Samudra is to be reversed. Thus in the first line we shall have all short letters. Then in each succeeding line a long letter should be written under the first short letter in the upper line, the rest being copied as they are in the upper line. Under the letters which precede the first short letter in the upper line, we should naturally write down all short letters in the lower line and go on in this manner until we get all long letters in the last line.
11. The sixth or the Pätāla Prastara consists of five figures representing, respectively, 1 the total number of the permutations of a metre; 2 the
