+ The first absolute largest palindromic prime. Absolute largest, i.e., formed from 9's and the middle digit 8, and, so, larger than any palindrome with the same number of digits. Palindromes of this pattern are expressed by the form 10^(2k+1)-10^k-1. [Silva]

+ The smallest palindromic maxsum prime. A "maxsum prime" is a n-digit prime whose sum of digits is the maximum possible. [Green]
