HCP has only 2 types of planes with an alternating...ABABABAB...arrangement. A CCP structure contains three types of planes, with an alternating...ABCABCABC...arrangement.

CCP shows 3-fold axis of symmetry in 3-diemension while HCP shows 6-fold symmetry axis in 3-dimension.

sir in types of unit cell we studied it can be of 4 types i.e primitive, face centred, body centred and end centred, but while studing 3D close packing it was told that it can be of 3 types i,e. simple(primitive) cubic unit cell, hcp and ccp. but i am not able  to understand that hcp is a type of unit cell or it is one of the 7 crystal system or somthing else?and if it is type of unit cell then why it is not taught under the topic types of unit cell. and if it is a crystal system then what about the rest 6 crystal system, then why rest 6 crystal system does not comes under 3 dimensional close packing?
