  We show how to construct embedding space three-point functions for operators
in arbitrary Lorentz representations by employing the formalism developed in
arXiv:1905.00036 and arXiv:1905.00434. We study tensor structures that
intertwine the operators with the derivatives in the OPE and examine properties
of OPE coefficients under permutations of operators. Several examples are
worked out in detail. We point out that the group theoretic objects used in
this work can be applied directly to construct three-point functions without
any reference to the OPE.
