    78   You should now be able to --

    79 \begin{itemize}

    80 \item make sets from lists

    81 \item input sets directly

    82 \item perform operations like union, intersection, symmetric difference

    83 \item check if a subset of another

    84 \item check containership, length and other properties similar to lists
