Set -- the class of all sets

Set -- the class of all sets

The type Set is a member of the class Type. Each object of class Set is also a member of class Tally.

More general types (whose methods may also apply) :

Tally -- the class of all tally results

HashTable -- the class of all hash tables

Functions and methods returning a an object of class Set :

new Set from List

Set * Set -- intersection of sets

Set ** Set -- Cartesian product

Set + Set -- union

Set ++ Set -- disjoint union of sets

Set - Set -- set difference

Methods for using an object of class Set :

isSubset(Set,Set) -- whether something is a subset of another

product Set -- product of elements

Set #? Thing -- test set membership

subsets Set -- produce all the subsets

subsets(Set,ZZ) -- produce all the subsets

sum Set -- sum of elements

toList Set -- list of elements
