OK. Got it. We’re not going to have a lot of Christmas Tree puzzles this week. We’re going to have Christmas Threes instead.
O Christmas Three, O Christmas Three
You’re both Mersenne and Fermat-y
O Christmas Three, O Christmas Three

Not only used in Tapa clues,
But also used alongside twos.
O Christmas Three, O Christmas Three!
You’re both Mersenne and Fermat-y!
