Symmetries of Knotted Hypothetical Molecular Graphs
hypothetical molecular graphs, symmetries of knots, achiral
We obtain examples of knotted hypothetical molecular bond graphs which are achiral but have no topologically accessible symmetry presentations. Such a graph is one which can be deformed to its mirror image, yet it cannot first be deformed to a position which can then be rotated to its mirror image.
