Coherent configurations were earlier studied by \textit{D. G. Higman} [Linear Algebra Appl. 93, 209-239 (1987; Zbl 0618.05014)]. The parametric relations for the coherent configurations of type \(\left({2\atop\;}{2\atop n}\right)\) and related designs are established here. It is shown that the Witt design \({\mathcal S}(5,8,24)\) is determined by the association scheme on its blocks and the family of designs based on systems of linked symmetric designs is characterized.
