Nature of problem:
Generating functions enumerating L-harmonics are useful in providing polynomial bases and constructing missing label operators for semisimple groups reduced according to the principal SU(2) subgroup. LHARM can be used to construct such generating functions for arbitrarily large L.
Recursion procedure generating FL from FL-2.
There are no restrictions but some modifications are needed in the listed program for L>13.
Compile time was 3s. For L=5, CPU=7. For L=13, CPU=72.
