Characters of oDPPPfJ : o , D , P , P , P , f , J . Reversed order: J , f , P , P , P , D , o → concatenated: JfPPPD o — no, that’s JfPPPDo (no space). Yes: JfPPPDo .

GHpVhSsiB → BisshVpHG aenBx → xBnea 57 → 75 tXZnh → hnZXt oDPPPfJ → JfPPPD o – no, I made a mistake: o D P P P f J reversed is J f P P P D o . As a string: JfPPPD o ? That's not right. Let's do it carefully: GHpVhSsiB aenBx 57 tXZnh oDPPPfJ

G(7) → T(20) H(8) → S(19) p(16) → k(11) V(22) → E(5) h(8) → s(19) S(19) → H(8) s(19) → h(8) i(9) → r(18) B(2) → Y(25) Characters of oDPPPfJ : o , D , P , P , P , f , J

So reversed words: BisshVpHG xBnea 75 hnZXt JfPPPDo GHpVhSsiB → BisshVpHG aenBx → xBnea 57 →

57 stays as 57 because digits unaffected.
