Descriptive Data: (report abuse)

LLR2 is a primality testing program for numbers of several specific forms. It uses Gwnum library by George Woltman, original LLR code by Jean Penné, hardware error check by Robert Gerbicz and test verification scheme by Pavel Atnashev with verifiable delay function by Krzysztof Pietrzak.

Surname: LLR2 (used for alphabetizing and in codes).
Unverified primes are omitted from counts and lists until verification completed.
