Abstract
To take care of the fact that a normal subgroup of a normal subgroup n eed not be normal in the original group, the concept of group extensio ns is generalized to the concept of group enlargements. This is relate d to wreath products. Applications are made to the calculation of alge braic fundamental groups.
