In mathematics, a permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements. The word "permutation" also refers to the act or process of changing the linear order of an ordered set. Permutations … See more Permutations called hexagrams were used in China in the I Ching (Pinyin: Yi Jing) as early as 1000 BC.
