Template Riesel prime

Display of current data for Riesel primes kbn-1, comments will be displayed as references at the bottom.


{{Riesel prime


  • Rk: the k-value of kbn-1
  • Rb: the b-value of kbn-1
  • RCount: the number of n-values given
If no count is given, this will be automatically counted. If given and differs from automated value, a warning will be shown.
  • RNash: the Nash weight
  • RMaxn: highest n-value of continuous searched range (from n=1)
  • RDate: last date of edit
  • RReserved: person(s) who reserved this sequence (comma separated)
  • RMultiRes: number of Template:Multi Reservation: RMaxn and RDate will be taken from there
  • RNlist: list of every n-value (one per row) with comments
  • RRemarks: any helpful text or links for this sequence
  • RSieve: if set a zip-file can be uploaded (filename is given then) if not available; if exists file is downloadable

Categories set

In case of the following conditions special categories will be set automatically (b = 2 only)::

  • If k-value is disvisible by 3 → category Riesel 3k is set
  • If k-value is disvisible by 15 → category Riesel 15k is set
  • If k-value is disvisible by 2145 → category Riesel 2145k is set
  • If k-value is disvisible by 2805 → category Riesel 2805k is set
  • If RCount=0 & RNash=0 & RMaxn=0 → category Riesel number is set

Any base (here given for base 2 only):

The category Riesel prime for base b is set by default.
