%N Smallest prime that can be formed using the digits of first 3n+1 numbers, or 0 if no such number exists.
%C The digits of first 3n and first 3n1 numbers yield a composite number which is a multiple of 3. Conjecture: No entry is zero. Subsidiary sequence: the number of distinct primes that can be formed using the digits of first 3n + 1 numbers.
