Function: multinomial (<r>, <part>) where <r> is the weight of the partition <part>. This function returns the associate multinomial coefficient: if the parts of <part> are <i_1>, <i_2>, ..., <i_k>, the result is <r>!/(<i_1>! <i_2>! ... <i_k>!).
There are also some inexact matches for multinomial. Try ?? multinomial to see them.
