%N A074675 Three-digit distinct-digit primes.
%C A074675 There are exactly 97 four-digit primes with all distinct digits, so the 
               sequence is finite.
%e A074675 a(1)=103 and a(510)=983 because these are the first and the last three-digit 
               primes with all distinct digits.
