The rules in this category are known in Pali as pāṭidesanīya, “entailing acknowledgement”. There are four such rules for the monks, none of which are shared with the nuns. What distinguishes these rules from the pācittiyas is the manner of confession. For these rules the confession is done using a unique formula, with the second rule being the only one in the Monastic Code where all the offenders confess together as a group.
