NettetAbstract: Congruential sieves have been constructed as software programs or as physical devices for nearly a century. Factor stencils were used by D.N. Lehmer in his table of prime numbers constructed early in the 20th century, and a sequence of special purpose electrical, electro-mechanical, and electronic devices were built by D.H. Lehmer … NettetLehmer sieves are mechanical devices that implement sieves in number theory. Lehmer sieves are named for Derrick Norman Lehmer and his son Derrick Henry Lehmer. The father was a professor of mathematics at the University of California, Berkeley at the time, and his son followed in his footsteps as a number theorist and professor at Berkeley.
