For further advances to be made in theoretically describing QCD processes at high energies and bounded momentum transfers, it is necessary to understand the structure of three-Reggeon cuts and to be able to calculate their contributions to QCD amplitudes. At the present time, the theory of such cuts is still in its infancy. The existing approaches to calculating contributions of three-Reggeon cuts to elastic-scattering amplitudes are discussed in the present article.
