REGULAR PROJECTIONS OF KNOTTED HANDCUFF GRAPHS
Kouki Taniyama, Chizu Yoshioka · Journal of Knot Theory and Its Ramifications · 1998
We construct an infinite set of knotted handcuff graphs such that the set of the regular projections of the handcuff graphs in the set equals the set of the regular projections of all knotted handcuff graphs. We also show that no finite set of knotted handcuff graphs have this property.
