The multinomial coefficient is a generalization of the binomial coefficient. Given a list of number $k_1,\ldots,k_l$, the multinomial coefficient is $n!/(k_1!\ldots,k_l!)$ where $n = \sum k_i$. The multinomial coefficient is calculated because it gives the numbers of tabloids for a given partition.
The list of numbers used to calculate the multinomial can be given as a list, a partition or a tally. This last option was added to optimize this calculation.
