Abstract

The Harary reconstruction conjecture states that any graph with more than four edges can be uniquely reconstructed from its set of maximal edge-deleted subgraphs. In 1977, M\"uller verified the conjecture for graphs with nn vertices and nlog2(n)n \log_2(n) edges, improving on Lov\'as's bound of log(n2n)/4\log(n^2-n)/4. Here, we show that the reconstruction conjecture holds for graphs which have exactly one cycle and and three non-isomorphic subtrees.
