This Is Not The Page You Are Looking For

This entire hierarchy has been moved to http://theurgy.digex.net:8000/inv/ from http://www.cis.upenn.edu/~lwl/inv/

The relative URLs should still be the same.

If you are using Netscape, you will be taken to the new Invocations page in thirty seconds; otherwise, click on this link.
