In abstract algebra, the sedenions form a 16-dimensional noncommutative and nonassociative algebra over the real numbers, usually represented by the capital letter S, boldface or blackboard bold .
The sedenions are obtained by applying the Cayley–Dickson construction to the octonions, which can be mathematically expressed as {{tmath|1= \mathbb{S}=\mathcal{CD}(\mathbb{O},1) }}. As such, the octonions are isomorphic to a subalgebra of the sedenions. Unlike the octonions, the sedenions are not an alternative algebra. Applying the Cayley–Dickson construction to the sedenions yields a 32-dimensional algebra, called the trigintaduonions or sometimes the 32-nions.
