what is the coordination number in hcp and ccp arrangement????

 coordination no. of hcp arrangement is 12 and that of  ccp is 12. refer the pattern of fcc it is ABCABCABC..... type structure i n which central atom in B type is surrounded by 6 atoms from side 3 from upward and three from downward.  in ccp A and C has structural difference . but both has same no. of atoms.

in hcp there is ABABAB.................. type pattern where central atom at B is surrounded by 6 atoms of B ; 3 of A from upward and 3 atoms of A From downward.
