| Description |
A connected graph G, whose 2-connected blocks are all cliques (of possibly varying sizes) is called a block graph. Let D be its distance matrix. By a theorem of Graham, Hoffman and Hosoya, we have det(D) not equal 0. We give a formula for both the determinant and the inverse, D(-1) of D.
