%N Primes of the form smallest multiple of n followed by a 1.
%C Conjecture: {(a(n)-1)}/{10n} < n, or a(n) < 10*n^2 + 1.
%C The conjecture holds for 2 < n < 10^8. Heuristically, the chance of its failing for larger n is about 10^-300000 based on the integral of exp(-2.5*x/log(x)^2) using the Poisson model for numbers coprime to 10. - _Charles R Greathouse IV_, Feb 15 2011
