I'm confident in my equations, so we'll need to be more precise to figure out where we agree, and where we disagree. I assume the first equation, for the limit of the SuperFunction of 2sinh is agreed upon, but one never knows. Using this equation, the value of SuperFunction(0)=1.058049043.... I think the two equations after that are also fairly obvious, and I assume you also agree with them.

Then substitute n with the inverse superfunction of n. Here the intent is to normalize so that SuperFunction(0)=n. And finally substitute n with the iterated exponentiation of n. This is equation is the equation I used to generate TommySexp; the only remaining step is iterating the ln function, and the equation I used for k. Do you still disagree with this equation? If so, why is this equation invalid, and is there another equation would you use instead? And does that alternative equation give identical values? I don't read minds, and I would be extremely interested in an alternative equation if you have one, because I would like to compare the two equations! They're probably equal!

The other thing I posted was the shorthand substitution equation for k, which quickly converges to k+n, where k converges to k=0.067838366... for values of n>=2. At that point, after applying the iterating ln function, we have the equation you disagreed with, which still seems completely correct to me.
