Mv 2.33

Translated from the Pâli by T. W. Rhys Davids and Hermann Oldenberg

'In case, O Bhikkhus, there assemble in a certain residence on the day of Uposatha a number of resident Bhikkhus, four or more; they know that other resident Bhikkhus are about to enter the boundary. They know that other resident Bhikkhus have entered within the boundary. They see other resident Bhikkhus who are about to enter, &c., who have entered within the boundary. They hear that other resident Bhikkhus are about to enter, &c., have entered within the boundary.'

Thus a hundred and seventy-five systems of triads are produced which refer to resident and resident Bhikkhus. (Then follow the same cases with regard to) resident and incoming Bhikkhus, incoming and resident Bhikkhus, incoming and incoming Bhikkus. By putting these words (successively) into the peyyâla, seven hundred triands are produced.
