Construction of Menon Designs with Parameters (784, 378, 182) and (900, 435, 210)

We describe a construction of symmetric designs with parameters (784, 378, 182) and (900, 435, 210) having an automorphism group isomorphic to $Frob_{; ; 29 \cdot 14}; ; \times Z_{; ; 13}; ; $ and $Frob_{; ; 31 \cdot 15}; ; \times Z_{; ; 14}; ; $, respectively. The derived designs of the constructed designs, with respect to the fixed block, are 1-rotational.
