Fun times. I once applied pagerank onto a set of 8000 math articles and ran the result as a web app in 2009/10.

As a gimmick, I created 36 groups, with group 1 containing the most important concepts:

Spoiler, the top ten concepts were:

Function · Set · Number · Integer · Real Number · Point · Property · Finite · Ring · Relation Theory

BTW: Glad the archive has a copy, because I do not.
