Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N Three-digit distinct-digit primes.
%C There are exactly 97 three-digit primes with all distinct digits, so the sequence is finite.

%e a(1)=103 and a(97)=983 because these are the first and the last three-digit primes with all distinct digits.
