Let x0 of type ι be given.
Assume H0: ordinal x0.
Let x1 of type ιο be given.
Claim L1: SNo_ x0 (PSNo x0 x1)
Apply SNo_PSNo with x0, x1.
The subproof is completed by applying H0.
Claim L2: SNo (PSNo x0 x1)
Let x2 of type ο be given.
Assume H2: ∀ x3 . and (ordinal x3) (SNo_ x3 (PSNo x0 x1))x2.
Apply H2 with x0.
Apply andI with ordinal x0, SNo_ x0 (PSNo x0 x1) leaving 2 subgoals.
The subproof is completed by applying H0.
The subproof is completed by applying L1.
Apply SNoLev_prop with PSNo x0 x1, SNoLev (PSNo x0 x1) = x0 leaving 2 subgoals.
The subproof is completed by applying L2.
Assume H3: ordinal (SNoLev (PSNo x0 x1)).
Assume H4: SNo_ (SNoLev (PSNo x0 x1)) (PSNo x0 x1).
Apply SNoLev_uniq with PSNo x0 x1, SNoLev (PSNo x0 x1), x0 leaving 4 subgoals.
The subproof is completed by applying H3.
The subproof is completed by applying H0.
The subproof is completed by applying H4.
The subproof is completed by applying L1.
