2nd half of "Vatican Saying 3 is at the top of 402r
Note that red capital T (tau) at the beginning: Τὸ ἡδόμενον κατὰ.... This implies to me that the Vatican Sayings manuscript seems to list part 1 and part 2 as "VS3" as two separate sayings. So, Vatican Saying 3A and 3B are what we also know as PD4.
