[GAP Forum] CentralIdempotentsOfAlgebra

[Neha Makhijani]

Hi,

Can somebody please tell me as to how we read the output
of CentralIdempotentsOfAlgebra function.

G:=SymmetricGroup(3);
Sym( [ 1 .. 3 ] )
K2G := GroupRing( GF(2), G );;
R2 := RadicalOfAlgebra(K2G);;
CentralIdempotentsOfAlgebra(K2G/R2);

[ v.4+v.5, v.1+v.4+v.5 ]

As in, what do these v's represent and how do I read them??

Thanks,
Neha
