%N Number of times most common digit of primes appears in first n primes.
%C Apart from the first four cases, 1 seems to be the most common digit of the first n primes.
%H Enrique Pérez Herrero, <a href="/A063273/b063273.txt">Table of n, a(n) for n = 1..1000</a>
%e a(6)=3 since first six primes are 2,3,5,7,11,13, so most common digit is 1 which has appeared 3 times.
