Definition: Let f be a function whose domain is the positive integers and whose range is the positive integers, and assume that f is one-to-one on the positive integers. Let sum(a_n) and sum(b_n) be two series such that b_n = a_(f(n)) for all n. Then sum(b_n) is said to be a rearrangement of sum(a_n).
