Opis:	It is shown that the graph $\Gamma_n$ that has the set of all $n \times n$ symmetric matrices over a finite field as the vertex set, with two matrices being adjacent if and only if the rank of their difference equals one, is a core if $n \ge 3$ . Eigenvalues of the graph $\Gamma_n$ are calculated as well.
