mme_omega_strassen_lt

Schönhage's bound in Strassen-preorder form: $\omega_{\mathrm{Strassen}} < 51/20 = 2.55$.

The matrix-multiplication exponent built from the restriction rank strassenRank satisfies $\omega_{\mathrm{Strassen}} < 51/20$. This is the analytic heart of Schönhage's 1981 theorem. It is deliberately stated over the Strassen preorder, because its proof runs through the asymptotic spectrum of tensors, Strassen's duality theorem, the asymptotic sum inequality, and the direct-sum construction $\langle n,1,m\rangle \oplus \langle 1,(n-1)(m-1),1\rangle$ — all theorems about that preorder.
