3.66

顯部別中，《僧祇》，初明制畜不同。若準今宗，不畜二衣俱提。尼下，示祇支制量。彼律一磔長二尺四，則計九尺六，廣四尺八。與前頗異。尼下，總列五衣。同別可見。

Under "Revealing Differences Among the Schools": in the Mahāsāṃghika-vinaya, it first explains differences in the rules for keeping [robes]. According to our school, not keeping either of the two robes is a pāyattika in both cases. "Nuns... below" indicates the prescribed measurements for the saṃkakṣikā. In that Vinaya, one span is two feet four inches, totaling nine feet six inches in length and four feet eight inches in width. This differs considerably from the preceding. "Nuns... below" lists all five robes together. The shared and distinct features can be seen.
