[seqfan] Rank of primes

[Eric Angelini]

Hello SaqFans,

Does one know if there is an applet somewhere on the Web which could tell me the rank of a prime number?

The link herunder (kindly provided by Neil), gives the answer for ranks going from 1 to 100 000. But if I want to know the rank of the prime number 147 787, for instance, how could I find it?
