- A subgroup H of a group G is said to be c-normal in G if there exists a normal subgroup N of G such that HN=G and H N Core(H) where Core (H) is the largest normal subgroup of G contained in H . In this paper we consider finite P-groups of order at most P4 where P is a prime and show that all of their subgroups are c-normal. Also we study some classes of finite groups whose all of subgroups are c-normal.
