$ \mathbb{}\text{If S is discrete and finite S = } \{S_1, S_2, S_3\}, \text{ S = } \{head,tail\}, S = \{win, lose\}, S = \{1,2,3,4,5,6\} $
$ \mathbb{}\text{If S is discrete but infinite, S = } \{S_1,S_2,S_3,...\}. \text{ Example: S = }\{1,2,3,4,...\} $
$ \mathbb{}\text{S = }\{\sin(2\pi*440t),\sin(2\pi*880t),\sin(2\pi*1320t),...\} $
$ \mathbb{}\text{Observe }\text{S = }\{\mathbb{R}\} \text{ is not routable; S = }\{0,1\} \text{ is not routable.} $
$ \mathbb{}\text{S = } f \in \mathbb{R} \geq 0 $
$ \mathbb{}\text{S = }\{\sin(2\pi*f*t) \mid 0 \leq f \leq \infty \} $

$ \text{Is } \mathbb{Z} \text{ routable? yes.} $
$ \mathbb{Z} = \{ 0,1,-1,2,-2,3,-3,... \} \text{ as opposed to } \mathbb{R} $
