The following definition is written in Python 3

def f(n): W=n+1 k=9 while W:     k*=k d=1 while W%(n+2)<=W//(n+2)**d%(n+2):d+=1 W=(2-W%(n+2)+abs(2-W%(n+2)))//2*W//(n+2)+(W%(n+2)-abs(2-W%(n+2)))//2*((W-1)*(n+2)**(d*k)+(W%(n+2)**d-1)*((n+2)**(d*k)-1)//((n+2)**d-1)) return k

My entry will be f^(f(100))(100), where f^n denotes iteration.
