Note how a -LRB- finite -RRB- multiset can also be considered as an unordered tuple : The tuples -LRB- a , b -RRB- and -LRB- b , a -RRB- are not equal because in tuples order is important .

A multiset can also be considered an unordered tuple : The tuples -LRB- a , b -RRB- and -LRB- b , a -RRB- are not equal , and the tuples -LRB- a , a -RRB- and -LRB- a -RRB- are not equal either .
