ProofByRefutation2Inclusion (python class)
See also
This section presents the ProofByRefutation2Inclusion python class.
This class models the inclusion of the proof-by-refutation-2 inference-rule in the target theory-derivation.
Punctilious users do not need to instanciate objects from this class. In effect, the TheoryElaborationSequence class exposes the proof_by_refutation_2 property, and instanciation is automatic when this property is accessed for the first time.
