LINKS

Table of n, a(n) for n=0..38.

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
