> ATT 3B2 There are a number of papers in pure mathematics authored by Doron Zeilberger and Shalosh B Ekhad. (See https://sites.math.rutgers.edu/~zeilberg/ekhad/papers.html https://sites.math.rutgers.edu/~zeilberg/ekhad/papers.html for a list. I don't think it's exhaustive) Shalosh B Ekhad is Zeilberger's computer, which once upon a time was an AT&T 3B1. In Hebrew, 3 is "shalosh" and 1 is "ekhad". (The 3B1 isn't actually much like the 3B2, despite the very similar names.)
