Conjectures on wirelength of hypercube into cylinder and torus

In the paper of Manuel et al. [8] the minimum wirelength of embedding hypercube into cylinder and torus were given as conjectures. In a recent paper of Rajan et al. [11] these conjectures have been proved. But there are logical flaws in the proof of lower bound of two conjectures and a constructional flaw in the upper bound of wirelength of hypercube into cylinder. In this paper we correct the constructional flaw and could not fix the logical flaws.
