| Dec 12, 2009 at 20:53 | comment | added | Greg Kuperberg | You removed the open problem label? | |

| Dec 4, 2009 at 4:45 | comment | added | Anton Petrunin | regular cover is the one you get from a free group action. | |
| Dec 4, 2009 at 4:36 | comment | added | Andrey Gogolev | I know :) So, what is a regular cover? | |
| Dec 4, 2009 at 4:09 | comment | added | Anton Petrunin | "An equilateral triangle with a loop at every vertex is a 3 fold cover. Right?" --- Right | |
| Dec 4, 2009 at 4:05 | comment | added | HJRW | Oh, you're talking about when you get equality. Sorry, I misread the previous version of the question. | |

| Dec 4, 2009 at 2:53 | comment | added | HJRW | What do you mean by "for many covers of figure-eight"? It seems clear that it's true for all finite covers of the wedge of two circles. (The number of edges in the maximal tree is m-1.) | |
