16061

This number is a prime.

+ The first term in a prime quadruplet whose four terms are Cyclops primes. Note that removing the 6's forms the smallest Cyclops prime, 101, with the same property. [Punches]

+ The only Cyclops palindromic prime formed by inserting a '0' between the square of a single-digit composite number n and its reversal. [Loungrides]

+ The first non-trivial palindromic Cyclops prime. The number 16061 in base HEX (hexadecimal) is 90209 in base TEN and the latter number is also a palindrome. [Ruiz-Huidobro]
