I need to know what base you're initializing for. The Ackermann function means you're probably initializing using base 2? hmmm, looking at your code, you're probably using base sqrt(2), which has two different superfunction solutions and fixed points of 2 and 4. I'll post some more after I do some experiments for base sqrt(2), along with your routine.

Code:`V(a,b,t) = {`

if (real(t)<1, return(exp2(t,exp2(-t,a)+exp2(-t,b))));

if (real(t)>=1, return(exp2(t,exp2(-t,a)+exp2(-1,b))));

}

exp2(t, a) = {

if (a==2, return(2));

if (a == 4, return(4));

if (real(a)>2, return(superf(isuperf(a)+t)), return(superf2(isuperf2(a)+t)));

}

I repeatedly get a cryptic Win32 error:

Code:`gp 4852 child_copy: linked dll data write copy failed`

This is my proposed "natural" extension to the Ackermann function, I'm confused as to why it won't plot.

I appreciate any help you can give me, thanks.
