On a class of algebras
Abstract
We introduce the notion of projective gruppal algebra that connects to every subgroup of order n of 
a n-dimensional algebra over K.In particular we classify the projective gruppal algebras 4-dimensional over a perfect field K studying the conjugacy classes of the groups 
and 
in
