Strategy

The goal statement for this puzzle is so short, I will copy it all here:

Your task is to determine how many pavings are possible for a rectangle using bricks of dimension 1 x 2 only.

A paving is a way to cover all the surface with bricks (partition)

Interesting! These bricks are the same 1 x 2 shape as the dominoes we just finished arranging. This puzzle asks us to count the number of possible solutions, just like we recently did in Constrained Latin Squares.

Put your study materials away. Keep your eyes on your own work. This is a test! Start your timer. You have 60 minutes.
