8Let $\ca{Pno}$ be the category of objects $(A, \alpha, a)$ where $A$ is a set, $\alpha : A \to A$ is a unary function, and $a \in A$ is a nominated Element and morphisms $\arr{(A, \alpha, a)}{}{(B, \beta, b)}$ which are functions $f: A \to B$ preserving the structure such that $f \circ \alpha = \beta \circ f$ and $f(a) = b$. 8Let $\ca{Pno}$ be the category of objects $(A, \alpha, a)$ where $A$ is a set, $\alpha : A \to A$ is a unary function, and $a \in A$ is a nominated element and morphisms $\arr{(A, \alpha, a)}{}{(B, \beta, b)}$ which are functions $f: A \to B$ preserving the structure such that $f \circ \alpha = \beta \circ f$ and $f(a) = b$.
