Description: Mapping from NN to N.. (Contributed by Jim Kingdon, 13-Jul-2021.)

Hypothesis

Ref	Expression
nntopi.n	|- N = |^| { x | ( 1 e. x /\ A. y e. x ( y + 1 ) e. x ) }

Assertion

nntopi	|- ( A e. N -> E. z e. N. <. [ <. ( <. { l | l <Q [ <. z , 1o >. ] ~Q } , { u | [ <. z , 1o >. ] ~Q <Q u } >. +P. 1P ) , 1P >. ] ~R , 0R >. = A )

Distinct variable groups:   x, y   z, A   z, N, y, x   u, l, z, y, x

Allowed substitution hints:   A( x, y, u, l)   N( u, l)

Proof of Theorem nntopi

Dummy variables w k v are mutually distinct and distinct from all other variables.
