| Dec 29, 2009 at 23:12 | comment | added | Tom LaGatta | Consider a ball with n ridges. For example, this object ( beads1.co.uk/Biagi-Beads/Biagi-BS-silver-symbols/thumbs/… ), along with a spherical cap at the top and the bottom. Let x be the point at the top of the cap. Let d be the distance to its antipodal point along one of the ridges. Then p(d,d/2,d/2) = n. | |

| Dec 29, 2009 at 8:29 | comment | added | Dima Fon-Der-Flaass | The problem is that these considerations are irrelevant: in the original question all values p(a,b,c) are explicitly required to be finite. | |
