Topological Chirality of Embedded Graphs

Kauffman proved that for any embedded graph G if we deform G, then the set T(G) will remain the same up to deformation. He then deduced the theorem below. 

Theorem. Let G be an embedded graph. If there is an element of T(G) which is topologically chiral and which cannot be deformed to the mirror image of any other element of T(G), then G is topologically chiral [9].
