A strongly regular graph is called primitive if both the graph and its complement are connected.
A theorem by Nash-Williams says that every k‑regular graph on 2k+ 1 vertices has a Hamiltonian cycle.
That is, a regular graph has a 1-factorization if and only if it is of class 1.
Every quasisymmetric block design gives rise to a strongly regular graph(as its block graph), but not all SRGs arise in this way.
A regular graph of degree k is connected if and only if the eigenvalue k has multiplicity one.
