  We propose new constructions for a two-dimensional ($2$D) perfect array,
complete complementary code (CCC), and multiple CCCs as an optimal symmetrical
$Z$-complementary code set (ZCCS). We propose a method to generate a
two-dimensional perfect array and CCC. By utilising mutually orthogonal
sequences, we developed a method to extend the length of a CCC without
affecting the set or code size. Additionally, this concept is extended to
include the development of multiple CCCs, and the correlation characteristics
of these multiple CCCs are identical with the characteristics of optimal
symmetrical ZCCS.
