14.76

「此復二種至餘五種戒」者，明二種僧別。四人已上名曰僧伽，於八眾中苾芻等三從此得故。補特伽羅是別人，謂餘五種從此得故。若勤策、勤策女，從二人得。若近事、近事女、近住，從一人得。

"This is again of two kinds … / the remaining five kinds of precepts" clarifies the distinction between the two kinds of saṃgha. Four or more persons are called a saṃgha, because among the eight assemblies, the three including bhikṣus and so forth obtain it from this. A pudgala is an individual person, meaning that the remaining five kinds obtain it from this. A śrāmaṇera and śrāmaṇerikā obtain it from two persons. An upāsaka, upāsikā, and upavāsastha obtain it from one person.
