Formula

a(n) = A004086(A000032(n)).

Example

81 is in the sequence because 7 + 11 = 18, which is 81 written backwards.

Mathematica

FromDigits[Reverse[IntegerDigits[#]]]&/@LucasL[Range[0, 50]]

Prog

(Magma) [Seqint(Reverse(Intseq(Lucas(n)))): n in [0..50]];
(PARI) a(n) = eval(concat(Vecrev(Str(fibonacci(n+1)+fibonacci(n-1))))); \\ Altug Alkan, Jan 17 2016
