3.38

Regarding showing the numbers, in the first section: The Dharmaguptaka text on fixed measurements is as cited above. Long and short are briefly shown as above: five strips with ten divisions (one long and one short); the other two robes are based on this, meaning seven strips with twenty-one divisions (two long and one short), nine strips with twenty-seven divisions, and so forth, increasing in succession. Relying on the Vinaya's fixed measurement, it details the two robes, while the long and short are based only on the five-strip [robe]; since the text mentions them together, one must know their two differences.
