N-category number

In mathematics, the n-category number of a mathematician is a humorous construct invented by Dan FreedSee [http://math.ucr.edu/home/baez/week255.html This Week's Finds 255] .] , intended to measure the capacity of that mathematician to stomach the use of higher categories. It is defined as the largest number "n" such that he or she can think about "n"-categories for a half hour without getting a splitting headache.
