I wanted to put a link to Wolfram Alpha. I have plotted $(n!)^{(1/n)}$ (with parentheses included). But
[this page](http://www.wolframalpha.com/input/?i=plot+%28n!%29^%281%2Fn%29)
produces
this page
As you see here the quoted page does not turn blue, nor is there a link.
Using the link in an address bar does give the right page though.
What is the error?
