Abstract :
In 1994, Yoshikawa introduced a method to describe a surface-link by a ch-graph. He classified surface-links represented by ch-graphs with at most three vertices and gave a table of surface-links whose ch-indices are less than or equal to ten. In this paper, we classify the surface-links with ch-graphs of square-type except a few examples.
