Let x0 of type ι be given.
Assume H0: SNo x0.
Apply SNoLev_prop with x0, x0 = PSNo (SNoLev x0) (λ x1 . x1x0) leaving 2 subgoals.
The subproof is completed by applying H0.
Assume H1: ordinal (SNoLev x0).
Assume H2: SNo_ (SNoLev x0) x0.
Apply SNo_PSNo_eta_ with SNoLev x0, x0 leaving 2 subgoals.
The subproof is completed by applying H1.
The subproof is completed by applying H2.
