Re:184270sqrt(3) + 78764sqrt(2) - 42555sqrt(6) - 1/12.

On a TI83 this looks like an integer. Jerry Uhl tried it on Mathematica.
Big deal. One, that is irrelevant here since the topic at hand was "lies
my calculator...
Secondly, even if there are no repeats to 60 decimal places, that does not
prove the expression is irrational. Only symbolic manipulation can do
that; Mathematica never can.
