Notation. We use - as a prefix operator with priority 358 corresponding to applying term minus_SNo.
Definition. We define add_SNo to be SNo_rec2 (λx y a ⇒ SNoCut ({a w y|w ∈ SNoL x} ∪ {a x w|w ∈ SNoL y}) ({a z y|z ∈ SNoR x} ∪ {a x z|z ∈ SNoR y})) of type set → set → set.

Notation. We use + as an infix operator with priority 360 and which associates to the right corresponding to applying term add_SNo.
