idlval  |-  ( R  e.  RingOps  ->  ( Idl `  R
)  =  { i  e.  ~P X  | 
( Z  e.  i  /\  A. x  e.  i  ( A. y  e.  i  ( x G y )  e.  i  /\  A. z  e.  X  ( (
z H x )  e.  i  /\  (
x H z )  e.  i ) ) ) } )
Distinct variable groups:    x, R, y, z, i    z, X, i    i, Z    i, G    i, H
Allowed substitution hints:    G( x, y, z)    H( x, y, z)    X( x, y)    Z( x, y, z)

Proof of Theorem idlval
Dummy variable  r is distinct from all other variables.
