Hey, I think a negative 2ND hyper operator might help (from now x???y).

SO:

2???2=4, obviously.

2???3=2????2????2=2????4, with x????y being hyper operator number -3. Hmmm.

2????4=2???3. And loop. OK then.

BUT 3???2 is quite weird to solve.

So how about 3???3?

3???3=3??2. Hmmm.

So then, 4???2=4????4.

From this point on, I need your help, Eners49.
