FORMULA
Conjectures from Colin Barker, Feb 18 2019: (Start)
G.f.: x*(1 + x + x^3 + x^6 - x^7 + x^8) / ((1 - x)*(1 - x^2 - x^4)).
a(n) = a(n-1) + a(n-2) - a(n-3) + a(n-4) - a(n-5) for n>9.
(End)
EXAMPLE
The word 0110 has the distinct palindromes (0, 010, 0110, 1, 11) and no other 4-length word has more, so a(4)=5.
