A225876
Composite n which divide s(n)+1, where s is the linear recurrence sequence s(n) = -s(n-1)+s(n-2)-s(n-3)+s(n-5) with initial terms (5, -1, 3, -7, 11).
The pseudoprimes derived from the fifth-order linear recurrence A225984(n) are analogous to the Perrin pseudoprimes A013998, and the Lucas pseudoprimes A005845.
For prime p, A225984(p) == p - 1 (mod p). The pseudoprimes are composite numbers satisfying the same relation. 4 = 2^2; 14791044 = 2^2 * 3 * 19 * 29 * 2237; 143014853 = 907 * 157679.
