That is called Hyper-hyperhypillion, if you asked.

Let H*(n)*(a,b,c,...,x,y,z) = H***...***(a,b,c,...,x,y,z) with n *'s

So that is equal to H*(10)*(10).

Now...

Let H*(n,0)*(n,0) equal H*(n)*(n), H*(n,m+1)*(n,m+1) equal HH*(n,m)*(n,m)(n), H*(a,b,…,c,1)*(a,b,…,c,1) equal H*(a,b,…,c)*(a,b,…,c), and H*(a,…,b,c,d)*(a,…,b,c,d) equal H*(a,…,b,H*(a,…b,c,d-1))*(a,…,b,H*(a,…b,c,d-1)).

Hyper-hyphyperhypillion = H*(10,10,10,10,10,10,10,10,10,10)*(10,10,10,10,10,10,10,10,10,10)
