Hockey Championships

At the 2021 World Hockey Championships, there are eight teams in Group A, each playing seven matches. There are 4 points for each team to gain points (3-2-1-0), but it is always paired with the opponent's points ( 0-1-2-3). How many points are there possible to split points after all 28 matches?

Correct answer:

n =  7.2057594037928E+16

Step-by-step explanation:

$$\begin{gathered} z=8\cdot 7/2=28 \\ n=4^z=4^{28}=7.2057594037928\cdot 10^{16} \end{gathered}$$
