PrimitivePythagorean

The historical Pythagorean equation with coprime legs; this predicate still permits the zero-leg triples.

Current library: Alpha v34, 4,223 checked-use theorems; Stable remains 432. Historical first admissions, original proof editions, and non-admitted aliases are preserved. Exact original first-admission records.

Readable signature

PrimitivePythagorean(x, y, z)

Exact expansion

(((x) * (x) + (y) * (y) = (z) * (z)) /\ (forall pff_divisor_frontier. (exists pff_left_frontier. (x) = pff_divisor_frontier * pff_left_frontier) -> (exists pff_right_frontier. (y) = pff_divisor_frontier * pff_right_frontier) -> pff_divisor_frontier = 1))

This node is conservative notation, not a theorem, axiom, predicate constant, or kernel rule. Its expansion remains in the unchanged first-order language.
