Another Increasing Function

Maybe you remember that back in January 2003, I offered you an increasing function that met two criteria (click the problem archives to see it). This month, I will challenge you with another increasing function that meets two criteria...


Let f map positive integers to positive integers with the conditions:



i) f(n+1) > f(n)

ii) f(f(n)) = 3n



Find f(955).
