RAM: 3000K words
Keywords: General purpose, Function, Dirac algebra, Gamma matrices, Symbolic calculation.
Classification: 4.7.

Nature of problem:
The calculation of multi-particle cross section involves the calculation of long traces of Dirac matrices. Even symbolic manipulation programs are not capable of doing this because of the large number of terms.

Running time:
Depends on the length of the trace, 30 minutes for 16 matrices.
