GAP4 group names

Can someone tell me where to find the "translation" of the GAP4 group names given by PARI as well as GAP4? I've looked on line, and the only reference appears to be a book that I don't care to purchase. Neither the GAP4 nor the PARI docs seem to contain the algorithm.

For example, "polgalois(x^8-3)" returns (among other things) [1/4.cD(4)^2]2, and polgalois(x^8-2) returns 2D_8(8)=[D(4)]2.

Thanks for any help.
