\begin{itemize}
\item A fully shielded transaction $T$ with change $T:z \rightarrow(z,z)$
\item A fully shielded transaction $T$ with no change $T:z \rightarrow z$
\item A shielded transaction $T$ with transparent change $T:z \rightarrow(z,t)$
\item A dehielding transaction $T$ with change $T:z \rightarrow(t,z)$
\item A dehielding transaction $T$ with no change $T:z \rightarrow t$
\item A shielding transaction $T$ with no change $T:t \rightarrow z$
\item A shielding transaction $T$ with shielded change $T:t \rightarrow(z,z)$

The above summarizes the most common transactions. Now say we want to describe a transaction which sends to 5 \zaddrs and 3 transparent addresses with no change:
$z \rightarrow z,z,z,z,z,t,t,t$ . To describe very large transactions subscripts can be used : $ z \rightarrow z_{52}, t_{39}$.
An individual transaction $T$ is a sub-graph of the full transaction graph $T \subset\mathbb{T}$ with vertex count of one.
More complex transactions such as $ t,t,t \rightarrow z $ are possible, which is
a shielding transaction most likely created by z\_shieldcoinbase. Raw transactions
are free to be as complex as allowed and some may be classified as shielding and
de-shielding at the same time, such as $ t,z \rightarrow t,z $ which is allowed
by consensus rules but no RPC method currently creates such a transaction in any
Zcash Protocol coin known to the authors. Even so, raw transactions could create
them and if/when they show up they will stand out greatly as very unique transactions.
