REGULAR PROJECTIONS OF KNOTTED DOUBLE-HANDCUFF GRAPHS
Ryo Hanaki · Journal of Knot Theory and Its Ramifications · 2009
A finite set of specific knotted double-handcuff graphs is shown to be minimal among those which produce all projections of knotted double-handcuff graphs. In addition, we show that a double-handcuff graph has no strongly almost trivial spatial embeddings.
