Marriage (card game) Marriage (card game) “Marriage” is a matching card game played with three decks of cards (156 Cards) played in Nepal, Bhutan and Nepali diaspora throughout the world. It is originally thought to have evolved from Indian Rummy (or Paplu), and is based on making sets of three or more matching cards, of the same rank (Trials), of the same rank and suit (Tunnels), or of three or more consecutive cards of the same suit (Sequences). This game should not be confused with German card game Mariage. A set is a group of at least three cards. "Dublee" is a set
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
