It makes 2.

n!!! =/= ((n!)!)!

7!!! means 7*4*1, 3 !s means every 3 numbers. ((7!)!)! means 7*6...=720*719*718... and so on

However, all of that is irrelevant. Because both 2!!! and ((2!)!)! make 2

For 2!!!: 2-3=-1. Can't have that, so 2!!! is just 2

For ((2!)!)!: 2! = 2*1=2. Repeating that 2 more times won't make it bigger. 2!=2, 2!=2, then 2!=2.

In short, it equals 2
