%N Lucas pseudoprimes whose reversal is prime.

%F A005845 INTERSECTION (A006567 UNION A007500). {n in A005845 such that A004086(n) is in A000040}. {n such that n | (L_n - 1), where n is composite and L_n = Lucas numbers A000032, and R(n) is prime}.

%e a(1) = 10877 = 73 * 149 because that is the 8th Lucas pseudoprime, and its reversal 77801 is prime.

%Y Cf. A000040, A004086, A005845, A006567, A007500.
