= Crank of a partition
{wiki=Crank_of_a_partition}
In the context of combinatorial mathematics, especially in the theory of partitions, the "crank" is a statistic associated with partitions of integers. It was introduced by the mathematician George Andrews and has applications in the study of partition theory and modular forms. A partition of a positive integer is a way of writing it as a sum of positive integers, where the order of addends does not matter.
