Orbit-Stabilizer theorem for continuous groups
Any reference reading on this? Somehow, I couldn't spot anything concrete via google; but I suspect quite a lot must have been studied (may be much less than the case of groups). |

Counting graphs on n vertices by chromatic number
@alexander: absolutely. implicit in this process will be somehow quotienting with the isomorphic sets - because for every graph, you can get the size of its isomorphic class - but that's where it will get messy I think. |

Counting graphs on n vertices by chromatic number
It seems that one should be able to count this for a given number N of vertices. compute a partition into different colors, and then compute how many ways edges can be formed between these partitions. The computation may be a bit messy, but seems doable. There may be some elegant way of getting it, of course, that I am not aware of. |

Degree of faces in a regular graph
Thanks much to both of you, Brendan, and Joseph. I understand that it is difficult to say much without the additional information such as connectivity. However, in the same vein, I am thinking it might be possible say a bit more than what's observed here; say, for instance, the number of faces with unbounded degree has an upper bound, or something like that. |

Degree of faces in a regular graph
This is one abstracted piece of a bigger problem of course, and at least on the surface I don't have any additional information. |

Computational complexity of Knot polynomials
Prof. O'Rourke, that is a beautiful modern reference; thanks very much. |
