A mathematical conjecture br or An ode to Vladimir Tonchev br br Is when quasi-symmetric designs br Reach two stage disjunctive testing br Upon subtracting the discrete numbers. br br They form systems of sets br And cyclotomy of self orthogonal br Codal length. br br Now, I know this means little br For those with a cerebral weakness br For unevenly distributed sets of digits br br However, were you faintly acquainted br With algorithms solving for optimal br Difference systems of sets br br and line spreads you’d be avoiding br such conflict of codes of length br in finite geometries.
