Enumeration of Regular Graphs
I don't think there's any closed form formula, but you can compare your results with the data in OEIS, such as here: oeis.org/A005638 (for 3-regular graphs) or here: oeis.org/A051031. This is indexed by the number of vertices, not edges, but of course for fixed k this is the same up to a factor of k/2. |

What's the name of this 2D cellular automaton?
Sounds familiar but I can't quite place it off the top of my head. Places to look would be the chapters on cellular automata in Gale's "Tracking the automatic ant", and of course Gardner's books and perhaps Hofstadter's collections from Sci Am. |

@Qiaochu: I'm really only talking about the interior case. It's then that the \osum is the same subspace as the sum but with the implied additional condition on the subspaces. |

how slow can the dimension of a product set grow?
So the circle S^1 has dimension 2 in your sense? If so, I don't know if this has a name but I certainly wouldn't recommend "dimension". |

Fundamental groups of noncompact surfaces
If I had been faster I would have proposed the same reference so you wouldn't have had to advertise your own book. I'm a fan :-) |
