[Reconstruction conjecture][1] says that graphs (with at least three vertices) are determined uniquely by their vertex deleted subgraphs. This conjecture is five decades old. Searching relevant literature, I found that the following classes of graphs are known to be reconstructible : - trees - disconnected graphs, graphs whose complement is disconnected - regular graphs - Maximal Outerplanar Graphs - maximal planar graphs - outerplanar graphs - Critical blocks - Separable graphs without end vertices - unicyclic graphs (graphs with one cycle) - non-trivial cartesian product graphs - squares of trees - bidegreed graphs - unit interval graphs - threshold graphs - nearly acyclic graphs (i.e., G-v is acyclic) - cacti graphs - graphs for which one of the vertex deleted graph is a forest. I recently proved that a special case of partial 2-trees are reconstructible. I am wondering if partial 2-trees (a.k.a [series-parallel graphs][2]) are known to be reconstructible. Partial 2-trees do not seem to fall into any of the above mentioned categories. - Am I missing any other known classes of reconstructible graphs in the above list ? - In particular, are partial 2-trees known to be reconstructible ? I asked this [question at cstheory][3] website also.
