The deck is 3 × 3 × 3 × 3 = 81 cards, since there are 4 properties with 3 possibilities each:
number one two three
fill hollow striped solid
color red green blue

If you pick 2 cards from the deck, there is only 1 card that forms a set with them.

If 21 or more cards from the deck are laid out, there has to be a set.
