%N Smallest interprimes of the form n*prime.

%C Interprimes of the form n*prime are in A075277-A075296 ( n = 2 - 21 ). Case n=1 is impossible. First 20 terms in the sequence are first terms in A075277-A075296.

%e a(8)=56 because 56 is the smallest interprime of the form 8*prime.

%Y Cf. A075277-A075296.
