四分律刪繁補闕行事鈔 1.537

1.537

上來明六人僧法，具述如上。次明五人眾法，恐濫行故簡異之。若界內五人者，索欲不開，問和答已，便白二差一五德竟，又重差第二人；不得牒二人，一時同法，以所為人不入僧數故。取自恣時，一五德同前坐，一五德展轉取自恣。若至坐處，二人共說。餘同前法。

The above has clarified the saṃgha rite for six persons, fully described as above. Next is explained the group rite for five persons, distinguishing it to prevent irregular practice. If there are five persons within the boundary, the solicitation of chanda is not permitted. Having asked for concord and received the response, one makes a motion-and-one-resolution karman to designate one five-virtue [monk], and then repeats it to designate the second person; one must not mention two persons in a single karman simultaneously, because the person designated does not count toward the saṃgha quorum. When receiving pravāraṇā, one five-virtue [monk] sits as before, and one five-virtue [monk] proceeds in turn to receive pravāraṇā. When reaching their seats, the two recite together. The rest is the same as the previous procedure.
