The nth Prime Page will now find any of the first 2.623˙10^{15} primes or
π(x) for x up to 10^{17}. 444444444 is the only ninedigit repdigit such that the product of itself and all truncations of itself minus one is prime. I.e., 444444444*44444444*4444444*444444*44444*4444*444*44*4  1 is prime. There are no such tendigit repdigits. [Opao]
