Using Brent's algorithm accelerated by binary splitting, Thomas
Papanikolaou was able to compute 1,000,000 decimals of Euler's constant
and, from this, 475006 partial quotients of its continued fraction,
proving that if gamma is a rational number, then its denominator must
exceed 10^244663. See the web page
