? belln;

 -- Function: belln (<n>)
     Represents the n-th Bell number.  `belln(n)' is the number of
     partitions of a set with <n> members.

     For nonnegative integers <n>, `belln(<n>)' simplifies to the n-th
     Bell number.  `belln' does not simplify for any other arguments.

     `belln' distributes over equations, lists, matrices, and sets.

     Examples:

     `belln' applied to nonnegative integers.

          (%i1) makelist (belln (i), i, 0, 6);
          (%o1)               [1, 1, 2, 5, 15, 52, 203]
          (%i2) is (cardinality (set_partitions ({})) = belln (0));
          (%o2)                         true
          (%i3) is (cardinality (set_partitions ({1, 2, 3, 4, 5, 6})) =
                                 belln (6));
          (%o3)                         true

     `belln' applied to arguments which are not nonnegative integers.

          (%i1) [belln (x), belln (sqrt(3)), belln (-9)];
          (%o1)        [belln(x), belln(sqrt(3)), belln(- 9)]


(%o1)                                true
