Number format English (en): 1,234,567.90

Example table for Sierpinski/Riesel problems

Data explantation

Data given in the table:

  • base b and some data for this base
    • conjectured k (CK) and the covering set in {}
    • algebraic factors (if exist) and k-values with these
    • remaining k-values or proven and search range in [] sorted by GCD
    • 10 highest primes/PRPs

[...]

Colors used

      proven and all primes are defined primes
      proven but some primes are only probable primes that have not been certified
      unproven
