There is an odd question on the main site: * https://mathoverflow.net/q/1/13653<sup>*</sup> The question is no longer required to fulfill its purpose as stated in the body.<sup>†</sup> Perhaps it ought to be deleted outright. As it is locked, one cannot even flag it for moderator attention and only moderators can do anything with that question. --- <sup>*</sup><sub>Yes, I did not follow that question's clear titular instruction.</sub> <sup>†</sup><sub>I bet you're curious what that purpose is. To find out all you have to do is disobey a simple directive.</sub>
