Horus Heresy (card game) the games produced by Sabertooth Games, each playable card has rarity information printed on to help determine how rare it is. The rarity is denoted by the number of small dots appearing at the bottom of the card, according to the following legend: When the game was first introduced, the starter pack (Base Set) included two play decks, one for the Loyalist and one for the Traitor side. Each contained 3 sector cards, 42 fixed cards, and 18 random cards (including three rares), all of which could theoretically be used. Additional enhancements to the starter were available, 9-card booster packs
Partition of a set into the connected components of the subgraph formed by the given set of edges. In this way, the lattice of partitions corresponds to the lattice of flats of the graphic matroid of the complete graph. Another example illustrates the refining of partitions from the perspective of equivalence relations. If "D" is the set of cards in a standard 52-card deck, the "same-color-as" relation on "D" – which can be denoted ~ – has two equivalence classes: the sets {red cards} and {black cards}. The 2-part partition corresponding to ~ has a refinement that yields the "same-suit-as" relation ~, which has
