I think [1[1/1,23]2] and [[[0],1] ] has level \(\psi(\psi_I(0))\)

[1[1/1,21/2]2] and [[[0]2,1] ] has level \(\psi(\psi_I(\Omega))\)

[1[1/1,21/1/2]2] and [[[[0]2]2,1] ] has level \(\psi(\psi_I(\Omega^2))\)

[1[1/1,21[1/2~2]2]2] and [[[[[0]2]2]2,1] ] has level \(\psi(\psi_I(\Omega^\Omega))\)

And [1[1/1,21[1[1~3]2~2]2]2] and [[[[0]3]2,1] ] has level \(\psi(\psi_I(\varepsilon_{\Omega+1}))\)
