WebThe bases of M(G) are the spanning trees of G; this assumes that G is connected. The circuits are simple cycles of the graph. The spanning sets are the connected sets of G. Lemma 1 Graphic matroids are regular. Proof: Take A to be the vertex/edge incidence matrix with a +1 and a 1 in each edge column (the order of the +1= 1 is unimportant). how do crypto hardware wallets work
