Lehmer

A Lehmer number modulo a prime p is an integer a with 1 ≤ a ≤ p − 1 whose inverse a ¯ within the same range has opposite parity. Lehmer numbers that are also primitive roots have been discussed by Wang and Wang in an endeavour to count the number of ways 1 can be expressed as the sum of two primitive roots that are also Lehmer numbers (an extension of a question of Golomb).
