Very nice.  Pauli

Thanks! It took me only five minutes or so to find this one on the 12C:

Five seconds on a 48G gave me this: 1146408/364913 The old regular 22/7 is a bit easier to remember. Mark

But neither of them use the digits 1 through 9 in order :)  Pauli

Archimedes' upper bound for Pi is better because it was obtained by reasoning rather than sheer luck. MathWord has plenty of Pi approximations to choose from: http://mathworld.wolfram.com/PiApproximations.html Regards, Gerson.  P. S.: The 33s gives instantly this even better and still easy to remember approximation:)
