          22 numbers marked with  p  are primes.
          20 numbers with an  *  are reported at OEIS (sequences A076335, A234594 and A180247).
          29 of the listed Brier numbers are covered by two different covering sets.

          An extended list including entries with more than 27 digits is also available.

          A catalogue describing all known basic Brier numbers  k  provides a label characterizing the number and its author, the
          correponding Sierpiński and Riesel coverings, the product  P  of the primes contained in the union of both sets covering
          the Brier number, and the modulus of the associated cycle.

          A  +  sign added to a label means that the number is not a basic one, but part of the respective cycle.
