Abstract
We present a chain of changes of variables that transforms a new integrable system found by Konno, Asai and Kakuhata, (J. Phys. Soc. Jpn., 74, No. 7, 1881–1882 (2005)) into a system of three PDEs that consists of the well-known Kaup-Newell system and a scalar first-order linear PDE on the background of the latter.
