There are 81 cards and 1,080 unique, unordered sets. Each pair of cards determines exactly one third card: 81 × 80 ÷ 6 = 1,080. The 15 types describe which of the four attributes are all different (the others are all the same).
The board preserves the supplied diagram’s layout, colours and symbols. It is redrawn with larger selection outlines and without the original yellow backgrounds: those mark a 20-card cap set (a collection containing no valid set), not the current selection.
