Actually in Richard Stanley's definitive book "Enumerative Combinatorics 
Volume 1" he uses {n^1,2^1,1^(n-2)} to indicate this multiset. This 
emphasizes equivalence under reordering. I like to keep the distinction 
between set brackets"{ } for sets  and parentheses ( ) for n-tuples 
--unlike some CAS that I will not mention.:-)
