2.1362

七十九。（亦因六群以手搏十七群故制。）戒名者，《僧祇》中，六群側掌為刀相，用擬於人，號為摶也。

Seventy-nine. (Also instituted because the group of six struck at the group of seventeen with their hands.) Regarding the name of the precept: in the Mahāsāṃghika-vinaya, the group of six turned their palms edgewise in the form of a blade and aimed it at a person; this is called "tuan" (搏, striking/lunging).
