An **ordinal sequence** is a mapping $\theta$ whose domain is an ordinal $\alpha$.

That is, the domain of $\theta$ is the set of all ordinals $\gamma$ such that $\gamma < \alpha$.

Such a sequence can be referred to as an **$\alpha$-sequence**.

Hence an **$\On$-sequence** is a mapping whose domain is the class of all ordinals $\On$.
