On Cohen–Macaulay modules over the plane curve singularity of type T 44

For a wide class of Cohen–Macaulay modules over the local ring of the plane curve singularity of type T 44 , we explicitly describe the corresponding matrix factorizations. The calculations are based on the technique of matrix problems, in particular, representations of bunches of chains.
