1949 Amer. Math. Monthly 56 623 Following Lehmer we shall call an integer n a pseudoprime if 2ⁿ≡ 2 (mod n) and n is not a prime.

1978 Amer. Math. Monthly 85 293 561 (= 3 x 11 x 17) is an ‘absolute pseudoprime’, i.e. it divides a⁵⁶¹ − a for every a.

1988 H. E. Rose Course in Number Theory i. 12 Extremely efficient methods exist for checking whether or not an integer is pseudoprime with respect to some fixed integer n.

1997 Sci. Amer. May 84/3 Unfortunately, every base has infinitely many pseudoprimes, so we can't just find a really good base and use only that.
