Every algorithm in GAP is given in full for users to read and understand.
This one is stored in lib/algebra.gi and an overview is given of how it
works in that file (around line 3400). At the end of the overview is
the comment:
## For a more elaborate description we refer to "W. Eberly and M.
## Giesbrecht, Efficient Decomposition of Associative Algebras,
## Proceedings of ISSAC 1996."
After that comment, the full source code of CentralIdempotentsOfAlgebra
is given.
