In this paper, we introduce six basic types of composition of ternary relations, four of which
are associative. These compositions are based on two types of composition of a ternary relation
with a binary relation recently introduced by Zedam et al. We study the properties of these
compositions, in particular the link with the usual composition of binary relations through the
use of the operations of projection and cylindrical extension
