Simple k-Angulations

Simple *k*-Angulations is the family of simple 2-connected plane graphs such that all faces (including the outer face) have size equal
to the *k*. This page contains the exhaustive list of *k*-angulations
for *k=3,4,5,6,7,8,9,10* of small orders.

Planar Hypohamiltonian Graphs

Planar hypohamiltonian
graphs are the family of plane
graphs that are not hamiltonian
but removing any vertex make them hamiltonian. This page contains a list of smallest
known planar hypohamiltonian graphs.
