The 8-cage (3) may be defined as the simplest cubic graph having no circuit of fewer than eight edges. To construct it we first observe that it must contain a tree T whose vertices are of degrees 1 and 3 and in which each vertex of degree 1 is separated by an arc of just three edges from a central edge AB. These properties fix the structure of T uniquely.
