I have commutative rational algebras that are supposed to be semisimple

over some cyclotomic field. How can I find this structure? Extending

coefficients to "Cyclotomics" and using "CentralIdempotentsOfAlgebra" gives

a crash, apparently because GAP cannot factor polynomials over cyclotomics.

Is there some way to find where the implementation of a function is in the

library? For instance material related to structure constant tables for

algebras occurs in at least three different files. Reading the code can be

very helpful, but I can't always find it.

Thanks, Frank Quinn
