Given a Lucas sequence with parameters and , discriminant , and roots and , the Sylvester cyclotomic numbers are
(1) |
where
(2) |
is a primitive root of unity and the product is over all exponents relatively prime to such that .
For small , the first few values are
(3) |

(4) |

(5) |

(6) |
|||
(7) |

(8) |

(9) |
These numbers satisfy
(10) |
where as usual .
Ward (1954) gave a primality test involving these numbers.
