Almost any time I use Mathematica, I wind up with many sequences of
integers, rationals and sometimes even irrationals. (I was missing
Mathematica, last week I didn't get to use it at all because I don't have it
at work nor at home).
Half of those sequences turn out to be wrong because I misunderstood the
concept I was investigating or because I messed up the computational logic
by incorrectly nesting one of the steps (and that's when I don't create an
infinite loop). Like this morning, I was trying to compute Hilbert primes
but I was using the built-in GCD, which as you know, operates on Z rather
than H. As you can imagine, the sequence I was getting was primes of the
form 4k + 1 with a 9 stuck in between 5 and 13, but with none of the
"composite" Hilbert primes. That sequence is not in the OEIS
