Nature of problem:
Values for angular momentum coupling coefficients are required for a variety of physical situations.
The program represents all numbers as arrays of prime factors, and the necessary arithmetic is performed on those arrays.
Large values of angular momenta may cause overflows.
The results are expressed in rational form (the quotient of two integers multiplied by the square root of the quotient of two integers).
Typical time <= 1s for a single coefficient.
