lsatset.v  |-  V  =  ( Base `  W
)
lsatset.n  |-  N  =  ( LSpan `  W )
lsatset.z  |-  .0.  =  ( 0g `  W )

Assertion
Ref Expression
lsatset  |-  ( W  e.  X  ->  A  =  ran  ( v  e.  ( V  \  {  .0.  } )  |->  ( N `
 { v } ) ) )
Distinct variable groups:    v, N    v, V    v, W    v,  .0.    v, X
Allowed substitution hint:    A( v)

Proof of Theorem lsatset
Dummy variable  w is distinct from all other variables.
