The smallest Gilda prime. Note that if a Fibonacci-like sequence is formed with the first term equal to the absolute value between the
digits of 29 (i.e., 7) and the second term equal to the digit sum of
29 (i.e., 11) then 29 itself occurs as a term in the sequence: 7, 11, 18, 29. [Russo]
The smallest multidigit prime whose product of digits of its cube is also a cube. [Russo]
The largest known prime p such that 5p contains no pair of consecutive equal digits. [Russo]
