Plot of funciton SuTra, id est, Superfunction of the Trappmann function $\mathrm{Tra}(z)\!=z\!+\!\exp(z)$.

The thick blue curve shows $y\!=\!\mathrm{SuTra}(x)$

The thin dark brown curve shows the asymptotics, $y\!=\! - \ln(-x)$

The additional horizontal gridline shows $1\!+\!\mathrm e=\mathrm{SuTra}(2)$
