Abstract
In this paper, we prove that all but one of the components of the transfer
digraph D? m needed for the enumeration of 2-factors in the rectangular,
thick cylinder and Moebius strip grid graphs of the fixed width m (m ? N)
are bipartite digraphs and that their orders could be expressed in term of
binomial coefficients. In addition, we prove that the set of vertices of
each component consists of all the binary m-words for which the difference
of numbers of zeros in odd and even positions is constant.
