+ The smallest prime p such that reversal(p*reversal(p)) is prime. [Loungrides]

+ The largest distinct-digit reflectable prime. Note that there are only five such primes, i.e., 3, 13, 31, 83, 103. [Loungrides]

+ (103, 107) is the first cousin prime pair (p, q) such that p^2+q^3 -/+ 1 is a twin prime pair, i.e, (1235651, 1235653). [Loungrides]

+ The product of all primes with distinct prime digits minus 103 is prime. [Loungrides]

+ The only prime that can be represented in four ways as sum of a double-digit prime plus the reversal of another double-digit prime, i.e., 11+R(29), 29+R(47), 71+R(23), 89+R(41). [Loungrides]

+ The smallest multidigit prime that can be represented as an illustration of Wilson's theorem as the only 3-digit such prime, i.e., (6!+1)/7=103. [Loungrides]
