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]))]
