A cover for a group G is a collection of proper subgroups whose union is the whole group G A cover is irodundant if no proper sub collection is also a cover, and is called maximal if all of the mnoubers are maximal subgroups, For an integer n>2, a cover with n members is called an n cover In this paper we investigate the maximum value of Ψ on the set of groups with a maximal irredundant 6 cover with core free intersection
