TitleExactly 14 intrinsically knotted graphs have 21 edges.
Abstract
Johnson, Kidwell and Michacl showed that intrinsically knotted graphs have at least 21 edges. Also it is known that K7 and the 13 graphs obtained by triangle-Y moves from K7 are intrinsically knotted graphs with 21 edges. In this paper, we proved that only these 14 graphs are intrinsically knotted graph with 21 edges.
