What's wrong with the surreals?
I actually remember one more disadvantage mention by Conway: equality is a defined relation, and a pretty subtle one at that. It's not too easy to figure out when two expressions for surreal numbers are actually equal. |

What can be tiled by T-tetrominoes?
The paper "Tiling rectangles with T-tetrominoes" by Korn and Pak seems to present some progress for non-rectangular simply-connected regions, mainly Theorem 11 in section 8. It doesn't seem like they have a complete answer though. citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.70.6847 |

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. |
