For N=2n+k, with k even and k>n, a(n) is the number of Carlitz palindromic compositions having k as a central summand. For N=2n+1+k, with k odd and k>n, a(n) is the number of palindromic compositions having k as a central summand. - Gregory L. Simay, May 15 2022

| EXAMPLE
|
Enumerate the Carlitz palindrome compositions of 13 for which the central summand is the greatest part: 13; 1,11,1; 2,9,2; 3,7,3 & 2,1,7,1,2 & 1,2,7,2,1; and 4,5,4 & 3,1,5,1,3 & 1,3,5,3,1 & 1,2,1,5,1,2,1. Note that in these instances, the number of Carlitz palindromes so enumerated is 1+1+1+3+4 = a(0) + a(1) + a(2) + a(3) + a(4). - Gregory L. Simay, May 15 2022
