%N The n-th Champernowne prime (A176942) is found by concatenating the successive digits of the numbers 1,2,3,...,a(n) and possibly dropping some of final digits of a(n).
%e The third Champernowne prime A176942(3) = 123456789101112131415161 is obtained by concatenating the digits of the numbers 1,2,3,4,...,17, and then dropping the final digit; thus a(3) = 17.
%Y See A176942 for the Champernowne primes, A071620 for number of digits.
