Abstract: A Tatra association scheme is an association scheme arising from a symmetric bilinear form defined on the equivalence classes of nonzero $2$-dimensional vectors modulo some subgroup of the multiplicative group of a finite field. In the present paper, we prove that every such association scheme is $4$-separable, i.e., it is determined up to isomorphism by the tensor of its $4$-dimensional intersection numbers.
