Okay, I know I might be the only math geek to notice, but there is a (partial) list of radars that I found that are prime.
Kind of neat.:
"Enumerating all 668 palindromic primes of  length 7 is a task too daunting
so I will confine myself to the subset of the Palindromic Prime "Twin Pairs" of which there are 83 (duo's).
There are three palindromic primes in consecutive rows of three (triples) and one of four (quartet)."
