Ok, here:

&{&{3,3,3,3} &&&&& 3} =

&{&{3,3,{&{3,3,&{3,3,3,2},2},2} &&&&& 3} =

...

Unfold like BEAF unil you get the number in final form, n.

&{n &&&&& 3} =

&{n &&&& n &&&& n} =

Solve from the right.

&{n &&&& n &&& n &&& n &&& n...} with n &&&s.

And so on until you get:

&{n & n & n & n...}

Solve like BEAF, so define a "so-called" &{a,b(1)c}.

Finish that with &{a & b}, which is &{a,a,a,a...a,a,a,a} with b entries.
