MATH.7:12 - Relations
Uses MATH.4: extend preservation through finite expression construction.
Connects with MATH.5: distinguish extending generator images from constructing structure through an already reversible map.
Returns to MATH.2 when the representation combines elements: construct the quotient and determine the retained operation.
Uses MATH.6 for a failed preservation claim: exhibit the incompatible input or missing inverse direction.
Specializes the mathematical construction used by C.29.1: construct operations, relations and laws through a bijection. Use C.29 for their interpretation in another subject.
Connects with A.6.3.RT.OE: use the available expression rules to make the transported calculation operable; invention of a notation language is a further notational method.
