t (20th letter) ↔ G (7th) h (8) ↔ S (19) m (13) ↔ N (14) y (25) ↔ B (2) l (12) ↔ O (15)
t→s, h→g, m→l, y→x, l→k → sglxk no. Shift of +1: t→u, h→i, m→n, y→z, l→m → uinzm no. thmyl lbt rzdnt ayfl ly ppsspp
If we take thmyl as they ? t→t (same), h→h (same), m→e? m(13) to e(5) difference -8. y→a? y(25) to a(1) difference -24 or +2? Not consistent. t (20th letter) ↔ G (7th) h (8)
