N2 - © 2020 Elsevier B.V. Ivashchenko proposed the study of contractible transformations on graphs because of their applications to computer image analysis, theory of molecular spaces, and digital topology. He published five papers on this subject. Contractible transformations have recently been applied to topological data analysis. This paper presents a counterexample to several results that appeared in one of Ivashchenko's works.
