multiplicity procedure : This Maple procedure
computes the decomposition of the degree d polynomials on a tensor product space
as Schur modules.

polnomial making procedure
: This Maple procedure constructs the highest weight space of a Schur module.

in the ideal of the 4th
secant variety to the Segre product of P^2 x P^2 x P^3.

main_data.txt (990403b) : This is the output from
the Bertini run used for the decomposition of the zero set of the above degree 6
equations.

deg_9_salmon (23410546b) : This file contains a
basis of the
20 dimensional Schur module S_{3,3,3}C^3 \otimes S_{3,3,3}C^3 \otimes S_{3,3,3}C^4
