3.1110

第三沙彌尼中，初指同法。若下，顯別行。通明三眾，不獨沙彌。以尼三眾，不得獨行，故須簡伴。初制簡伴。若下，次聽兼帶。餘下，三制非類。即僧二眾，俗男女等也。

Under the third, regarding the śrāmaṇerikā, it first points to the shared rules. Below 'if', it reveals the distinct practices. This applies comprehensively to the three assemblies [of women], not solely to śrāmaṇerikās. Because the three assemblies of nuns are not permitted to travel alone, they must select companions. First, it regulates selecting companions. Below 'if', it next permits carrying [additional tasks]. Below 'the rest', the third regulates incompatible kinds, which are the two assemblies of monks, lay men and women, and so forth.
