Let D 2 n denote the dihedral group of order 2 n , where n ≥ 3 . In this article, we build upon the findings of Haggard and McCarthy who, for certain values of n , produced a vertex-minimal graph with dihedral symmetry. Specifically, Haggard consid

For n≥3, a smallest graph whose automorphism group is isomorphic to the generalized quaternion group is constructed. If n≠3, then such a graph has 2n+1 vertices and 2n+2 edges. In the special case when n=3, a smallest graph has 16 vertices but 44

A tessellation of the plane is face-homogeneous if for some integer $k\geq3$ there exists a cyclic sequence $\sigma=[p_0,p_1,\ldots,p_{k-1}]$ of integers $\geq3$ such that, for every face $f$ of the tessellation, the valences of the vertices incident

We establish an exact method for drawing fullerene patches in the hexagonal tessellation of the plane. Using these embeddings, we then provide a closed form equation for the total number of symmetric and near-symmetric fullerene patches, up to isomor

A tessellation is taken to be an infinite, 1-ended, 3-connected, locally finite, and locally cofinite plane map. When such a tessellation is the induced graph of a tiling of the hyperbolic plane, it is known that the asymptotic growth of the tessella

Large carbon molecules, discovered at the end of the last century, are called fullerenes. The most famous of these, C 60 has the structure of the soccer ball: the seams represent chemical bonds and the points where three seams come together represent

A tessellation is understood to be a 1-ended, locally finite, 3-connected planar map. The edge-symbol $\langle p,q;k,\ell\rangle$ of an edge of a tessellation $T$ is a 4-tuple listing the valences $p$ and $q$ of its two incident vertices and the cova
