+ A prime such that the sum of the squares of its digits is equal to the product of its digits. [Russo]

+ The smallest emirp made up of two palindromic primes: 11, 353. Note that the former is the digit sum of the latter, as is exactly the case with the smallest palindromic prime (17971) made up of two emirps: 17, 971; Moreover, 11353 is a concatenation of two primes in another way: 113, 53. [Beedassy]
