Lehmer made this conjecture in 1932, a couple of years after he had published his Ph.D. thesis, "On an Extended Theory of Lucas' Functions," in which he extended the theory of the Lucas (and companion Lucas) sequences to a larger family of sequences which now bear his name. In addition, he corrected some of the mistakes in the theory ...Emma Markovna Lehmer (née Trotskaia) (November 6, 1906 – May 7, 2007) was a mathematician known for her work on reciprocity laws in algebraic number theory.She preferred to deal with complex number fields and integers, rather than the more abstract aspects of the theory.

Beverly would eventually beat the bottle, craftily repel a stalker who had read about her in The Ring magazine, and, in her later years, undergo three replacement surgeries for her hip and shoulders. Encoding the digits of a Lehmer code into an integer is more complex, because each digit has a different radix. We want the mapping to be bijective (a one-to-one mapping without “holes”). The factoradic system is what we need, as explained via the following table.
