Aside from single digit primes, the first ten palindromic prime numbers are:
11 101 131 151 181 191 313 353 373 383 727
11
No, 11 is the only palindromic prime with an even number of digits.
11
727. The smallest palindromic number greater than 500 independent of primicity is 505.
The only 2-didgit palindromic prime is 11.
It is 77.It is 77.It is 77.It is 77.
They are called palindromic primes
1661 is a palindromic number.
"emirp" is "prime" spelled backwards. An emirp number is a prime number whose reverse is also a prime. However, palindromic primes are excluded. So 13 / 31 are emirp numbers.
11, 101, 131, 151, 181, 191
A two-digit non-prime palindromic number is a number that reads the same forwards and backwards, has two digits, and is not a prime number. An example of this is 22, as it meets all the criteria: it is two digits, reads the same in either direction, and is divisible by 1, 2, 11, and 22, making it non-prime. Other examples include 44, 66, and 88.
Example of a palindromic number is 16461.A palindromic number reads the same from both ends, which 16 fails to do.
