%N A121045 Least cluster prime greater than 10^n.
%C A121045 These numbers are useful for generating intermediate cluster primes because 
               the best algorithm for generating cluster primes requires starting 
               with a known cluster prime.
%Y A121045 Cf. A038134 (cluster primes), A039506 (number of cluster primes < 10^n),
