in the expansion of the polynomial 
. In combinatorics, the multinomial coefficient expresses the following: a) the number of possible permutations of 
elements of which 
are of one form, 
of another form
of the 
-th form; b) the number of ways of locating 
different elements in 
different cells in which cell 
contains 
elements, 
, without taking the order of the elements in any cell into account.
Particular cases of multinomial coefficients are the binomial coefficients.
