usage: gensymm [--options] A B C D FILENAME

Computes the generators for the symmetry group acting on 4-way tables
with 3-marginals. By putting one side length to 1, this includes
3-way tables with 2-marginals.

Options:
 -q, --quiet       No output is written to the screen

Output file:
 FILENAME.sym      generators for the symmetry group

Example:  Consider the problem of 3x3x3 tables with 2-marginals. Calling
  gensymm 3 3 3 1 333
produces the file '333.sym' containing the following lines.
