%N Integers n such that 10^n-29 is a prime number.

%C The next term, if one exists, is >100000. [From _Robert Price_, Apr 25 2011]

%C See Kamada link - primecount.txt for terms, primesize.txt for discovery details including probable/proven prime - search on "99971".

%e n = 8 is a member because: 10^8-29 = 100000000-29 = 99999971, which is prime.

%Y Cf. A089675, A095714, A092767.
