Is there any proof of infinitude of http://oeis.org/A007500 primes.
If you want to generate them here is trivial and naive python program.
def is_prime(n): i = 2 while i*i <= n: if n%i == 0: return False i = i + 1 else: return True print [x for x in range(1,200) if is_prime(x) and is_prime(int(str(x)[::-1]))]
