Addresses methods for determining whether or not a number is prime, by tracing the evolution of methods since the work of Lucas (1842-91), who first demonstrated that it could be done without the laborious task of trial division. Finds that, as in biological evolution, the modern tests have arrived through a complicated process of diversification and selection. Also seeks to rekindle interest in a quest that many non-specialists now consider resolved. Annotation c. by Book News, Inc., Portland, Or.

Describes the development and extension of fundamental idea of Edouard Lucas, a French mathematician and mathematical recreationist, that is still used today in the verification of the largest primes.
