摘要

In 1724, Goldbach wrote to Bernoulli that a product of three consecutive positive integers is not a square, thereby starting a series of investigations by mathematicians. In 1939, Rigge [1] and Erdős [2], independently, showed that a product of two or more consecutive positive integers is never a square.
