• Palindromic prime units W appearing four times in second-order fractal palindromic primes WxWmWxW, where part WxW is also a palindromic prime.at n=16A082599
• Smallest palindromic prime containing the digit string of n.at n=40A083982

• "2-ply" palindromic primes.at n=44A208362
• Dates after Jan 01 00 in chronological order which are palindromic when they are written in the format D.M.YY. The terms are listed as numbers (without the dots).at n=23A210890
