四分律刪繁補闕行事鈔 1.206

1.206

《五分》：斷事時，若在屋中，隨幾過出。若在露地，去僧一尋等並失。若房小不受僧者，聽在前後簷下庭中坐，雖不聞羯磨聲得成。又有七人：尼等四人狂等三人，皆不成欲。

The Pañcavargika-vinaya states: When deciding a matter, if inside a room, one steps out beyond however many [paces]; if in the open air, departing one fathom or more from the saṃgha, in all cases it is lost. If a room is small and cannot accommodate the saṃgha, they are allowed to sit under the front or rear eaves or in the courtyard; even though they do not hear the sound of the karman, it is valid. There are also seven persons: four kinds such as bhikṣuṇīs, and three kinds such as the mad; for all of them, chanda is invalid.
