四分律行事鈔資持記 2.2128

2.2128

定體中，初科。三五者，三即長離販賣，五即更加乞受。上三最數，下二次之，故云通犯否；餘戒非無，但是稀耳。

Under determining the entity, the first section: 'Three and five' means three refers to extra [robes], staying apart [from robes], and trading; five means adding begging and receiving. The upper three are the most frequent, and the lower two come next, hence it says 'whether universally violated or not'; the remaining precepts are not non-existent, but are merely rare.
