Removed a flawed argument

| Dec 29, 2009 at 9:27 | comment | added | Qiaochu Yuan | Dinesh, the way I interpreted your question you wanted to interpret the elements of S as elements of the group in one way (the function g in the notation I gave above), but that embedding you give requires that we have two functions g_1, g_2 instead. Was this your intended meaning? If so, symmetry is unnecessary, but I fail to understand how this can actually help you accomplish what you want since you've only turned the problem of computing f into the problem of computing h, g_1, and g_2. | |
