looks like someone is taking liberty with notation

5. Loser66

yes, this is binomial coefficient of 4th degree $$(x+y+z)^4$$

6. Loser66

and I have the combination of degree like 4,0,0, for x^4 y^0z^0 and the coefficient of this element is defined by that formula

7. Loser66

other element like x^2 yz will have the coefficient as $$\left(\begin{matrix}4\\2,1,1\end{matrix}\right)$$
