On an Algorithm for Obtaining All Binary Matrices of Special Class Related to V. E. Tarakanov's Formula
An algorithm for obtaining all n\times n binary matrices having exactly 2
units in every row and every column is described in the paper. After analysing
the work of the algorithm a formula for calculating the number of these
matrices has been obtained. This formula is known and has been obtained using
other methods, which by their nature are purely analytical and not
constructive. Thus a new, constructive proof of this known formula has been
obtained
