Mar 5, 2014 at 17:03 comment added Realz Slaw How can you divide by the elements in S? I assume you meant multiplication by modular inverse, which isn't actually division, unless it happens to divide exactly.
Oct 7, 2013 at 12:41 comment added Marc van Leeuwen Actually the mentioned $E_8$ computations were done in serial, not in parallel. The constraint was memory, not time: the CRT allowed $1$-byte coefficients to be used instead of $4$-byte integers, which given the huge amount of coefficients required was a crucial memory savings at the time.

However I did meet one computer-illiterate mathematician who believed me when I claimed that we counted them one at a time.
Jul 31, 2010 at 12:09 comment added Pete L. Clark I was just about to add the computation of the character table of E8 to the list when I saw this answer. So instead, a belated +1.
