With these definitions the multiset written as -LCB- a , a , b -RCB- is defined as -LRB- -LCB- a , b -RCB- , -LCB- -LRB- a , NUMBER@1 -RRB- , -LRB- b , NUMBER@2 -RRB- -RCB- -RRB- , and the multiset -LCB- a , b -RCB- is defined as -LRB- -LCB- a , b -RCB- , -LCB- -LRB- a , NUMBER@2 -RRB- , -LRB- b , NUMBER@2 -RRB- -RCB- -RRB- .

For example , in the multiset -LCB- a , a , b , b , b , c -RCB- , the multiplicities of the members a , b , and c are respectively NUMBER@1 , NUMBER@3 , and NUMBER@2 .
