四分律行事鈔資持記 2.77

2.77

別釋中，初科可解。入五中者，《僧祇》、《四分》，篇聚異名，昔多偏計；今但云五，無所局也。下亦合云，通入七攝；而云聚者，順今宗也。

In the separate explanation, the first heading is understandable. 'Entering into the five': the Mahāsāṃghika-vinaya and the Dharmaguptaka-vinaya have different names for classes and groups, and in the past there was often one-sided clinging; now it simply says 'five', without any limitation. Below it should also properly say 'comprehensively subsumed under the seven'; but stating 'groups' accords with our present school.
