The curve is the exponential of an exponential.
Its inverse is the logarithmic logarithm,
e.g. y = ln (ln x).
This
logarithmic logarithm is an approximation of the inverse
prime summation.
The Gompertz curve ^{1)} is
a linear form of the exponential exponential.
1) the Gompertz relation has the form of:
