Sifting limits for the Λ2Λ- sieve, Selberg's lower bound sieve, are computed for integral dimensions 1<Κ≥10. The evidence strongly suggests that for all Κ≥3 the Λ2Λ- sieve is superior to the competing combinatorial sieves of Diamond, Halberstam, and Richert. A method initiated by Grupp and Richert for computing sieve functions for integral κ is also outlined. © 2011.
