Harvey P. Dale, Table of n, a(n) for n = 1..168
FORMULA
Let p(n)=prime(n). If f:R->R is a continuous, everywhere-increasing function, such that f(x)=p(x) for every natural x and F = f^(-1) and if a(n) exists, then a(n) = p(ceiling(F(p(n)*(10^(p(n)-floor(log_10 p(n))-1))))). - Sam Alexander, Dec 31 2003
MATHEMATICA
