MATH.8:9 - Consequences
A known solution can supply a useful family without solving every transformed case independently. Orbit closure and stabilizers explain both the family and its repetitions. Separate orbits reveal a remaining construction problem rather than an apparent lack of progress in the same enumeration.
The gain depends on the cost of finding and applying the transformations. For a small isolated equation, direct calculation may finish sooner. For repeated or related questions, the shared preservation argument can save substantial work; the construction alone does not quantify that saving.
