missing sequence? number of embeddings of planar graphs

[Brendan McKay]

Neil means like this:

                  o
                / |
              /   |
            /     |
          /       |
  o     /     o   |
  |   /        \  |
  | /           \ |
  o --------------o

Same abstract graph but different drawing.

Brendan.
