Resumo
Ternary derivations, ternary Cayley derivations and ternary automorphisms are computed over fields of characteristic ≠2, 3 for the algebras A t obtained by the Cayley-Dickson duplication process. While the derivation algebra of At stops growing after t = 3, the ternary derivation algebra significantly decreases in the step from the octonions A 3 to the sedenions A4, revealing the symmetry lost on that stage.
