A palindromic number is a number whose digits, with decimal representation usually assumed, are the same read backward, for example, 5885. https://en.wikipedia.org/wiki/Palindrome
_pal_primes is a twitter bot based on my another project, _twin_primes. The bot posts the every next palindromic prime at 05:50 am&pm UTC.
I've calculated the palindromic primes up to 9989899. Thanks to https://primes.utm.edu/ for base data.
