gsp: central symmetry with digit mapping 123456789->987654321
4-cell exocet: any digit in r1c1 is forced into b2p58, b4p56, and b5p1379, likewise (rotated) for r1c9, r9c19
1r4c4&r1c9 = 7r1c9 – 7r3c78 = (7–2)r3c5 = 2r3c2 => –2r1c1&r4c4, by symmetry –8r9c9&r6c6
(3=9)r9c1 – 9r8c23 = (9–6)r8c5 = 6r8c78 – 6r9c9&r6c4 = 3r6c4 => –3r6c1, –3r9c4, by symmetry –7r4c9, –7r1c6
