%N A085451 Numbers n such that n and prime[n] together use only distinct digits.
%C A085451 There are exactly 101 such numbers in the sequence. Numbers with distinct 
               digits in A010784. Primes with distinct digits in A029743. The case 
               n and n^2 (exactly 22 numbers) in A059930.
%e A085451 3106 is in the sequence (and the last term) because it and prime[3106]=28549 
               together use all 10 distinct digits.
