Two subgroups A and B of a group G are cosubnormal if A and B are subnormal in their join A, B and are strongly cosubnormal if every subgroup of A is cosubnormal with every subgroup of B. We find necessary and sufficient conditions for A and B to be strongly cosubnormal in A, B and, if Z is the hype
