I need to construct a transformation matrix D (order nmp) from
the direct product of the real orthogonal matrices A (order n),
B (order m), and C (order p); as

          D = A X B X C

where the X represents the direct product operation. I looked in
Netlib, but no relevant software is listed. A co-worker
suggested I use Blas routines to generate the result, which at
least seems reasonable, though not necessarily trivial.
  Is there fortran software available for this problem?
  Are there any recommended computational strategies
to perform this type of calculation?
