It is shown that the block-intersection graph of a pairwise balance design with ),= l is edge-pancyclic given that its minimum block cardinality is at least 3.

Given a BIBD S = (V, B), its 1-block-intersection graph GS has as vertices the elements of B; two vertices B1, B2 ∈ B are adjacent in GS if |B1 ∩ B2| = 1. If S is a triple system of arbitrary index λ, it is shown that GS is hamiltonian.

In this paper we show that if G is a 2-connected graph having minimum degree n such that IV(G)1 L 2n + 1, then there exists a cycle in G having more than n(n -2
