N2 - Given a prime number p, Lehmer raised the problem of investigating the number of integers a ∈ {1, 2, . . . , p - 1} for which a and ā are of opposite parity, where ā ∈ {1, 2, . . . , p - 1} is such that a ā ≡ 1 (mod p). We replace the pair (a, ā) by a point lying on a more general irreducible curve defined mod p and instead of the parity conditions on the coordinates more general congruence conditions are considered. An asymptotic result is then obtained for the number of such points.
