text: Because every vertex is equivalent (or isomorphic) to every other vertex of the resulting graph, and since for the given $k$, $p$, $q$ and $r$ are determined, all of the graphs resulting from this procedure must be isomorphic (even though some of them will not be the plane drawing of this graph).
