Abstract
A new integrable equation is constructed by combining the recursion operator of the modified Calogero–Bogoyavlenskii–Schiff equation and its inverse recursion operator. The Painlevé is performed to demonstrate the complete integrability of the newly developed equation. Multiple-soliton solutions are depicted as manifestation of the integrability. We further show that this equation enjoys a variety of soliton solutions that include kinks, peakon, cuspon.
