Fifty cases of perceiving it is a group or not a group

^Kd.2.29.1 “This is a case, monks, where in a certain residence several resident monks, four or more, collect together on an Observance day. They know that there are other resident monks who have not arrived. Thinking of the rule, thinking of discipline, thinking that they are incomplete, they carry out the Observance and recite the Pātimokkha while they are incomplete. While the Pātimokkha is being recited by them, other resident monks, a larger number, arrive. Monks, the Pātimokkha should be recited again by those monks, and there is an offence of wrong-doing for the reciters.

^Kd.2.29.2 “This is a case, monks, … as in Kd.2.29.1 … a like number, arrive. What has been recited is duly recited, the rest should be heard, and there is an offence of wrong-doing for the reciters.

This is a case, monks as in Kd.2.29.1 … a smaller number, arrive. What has been recited is duly recited, the rest should be heard, and there is an offence of wrong-doing for the reciters.

^Kd.2.29.3 “This is a case, monks … When the Pātimokkha has just been recited by them and the assembly has not risen … part of the assembly has risen … the whole ^Vin.1.31 assembly has risen, and other resident monks, a larger number … a like number … a smaller number, arrive. What has been recited is duly recited, the entire purity should be announced in their presence, and there is an offence of wrong-doing for the reciters.
