This is the smallest 4-digit prime that produces 5 other primes by changing only its first digit (i.e., 2297, 4297, 5297, 7297, 8297 are primes). [Opao]
The reversal of 1297 is a prime square and the square of this prime has a prime reversal. Can you find the next prime like this? [Silva]
The largest non-titanic prime p of form p=6^n+1, where n is any number, and the only non-titanic prime for n a composite, (case n=4). The previous three primes are for n=0, 1 and 2. [Loungrides]
