Abstract: This paper is devoted to $\mathrm{3D}$ embeddable graphs, which are obtained from full spatial graphs by removing several edges incident to one vertex. For all such graphs we introduce the analogue of Conway–Gordon function $\omega_2$. We prove that its value is zero for all spatial graphs obtained from full graphs with no less than eight vertices. There are examples of graphs with six vertices, where the value of this function is equal to unity.
Keywords: spatial graph; Hamiltonian cycle basis; link.
