Question
मांना $\alpha=\frac{(4!)!}{(4!)^{3!}}$ तथा $\beta=\frac{(5!)!}{(5!)^{4!}}$ है। तो :
$ \alpha=\frac{(24) !}{(4 !)^6}, \beta=\frac{(120) !}{(5 !)^{24}}$
Let $24$ distinct objects are divided into $6$ groups of $4$ objects in each group.
No. of ways of formation of group $=\frac{24 !}{(4 !)^6 \cdot 6 !} \in \mathrm{N}$
Similarly,
Let $120$ distinct objects are divided into $24$ groups of $5$ objects in each group.
No. of ways of formation of groups
$=\frac{(120) !}{(5 !)^{24} \cdot 24 !} \in N$
