Thomas, you mastered the Answer to the Ultimate Question of Life, the Universe, and Everything - its rank is 42.

Thanks again to all of you!

As Curtis already mentioned, it's been a long time since the last prime for k=11 (found in March 2006) - almost exactly 8 years!

I believe that the question, if I remember rightly, was "WHAT DO YOU GET IF YOU MULTIPLY SIX BY NINE?".
