Is there some way to automatically force the descriptive sentence and the table to appear on the page.  One certainly use needspace, but I certainly wouldn't want to do this (say) every time I used the center environment.

Using \goodbreak seems to work fine;
viz.

    \end{center}
    \goodbreak
    Here is the truth table for the conjectured expression for~$s$:
    \begin{center}
      \begin{tabular}{ccc|cc}
        $x$&$y$&$\cin$&$x\oplus y$&
        $x\oplus y\oplus \cin$\\ 
        \hline
        ...


Here is an alternative way to do it, using a math display
to obtain the centering:

    \end{center}
   Here is the truth table for the conjectured expression for~$s$:
   \nobreak
   $$
       \begin{tabular}{ccc|cc}
        $x$&$y$&$\cin$&$x\oplus y$&
        $x\oplus y\oplus \cin$\\ 
        \hline
        ...

This latter way also reduces the amount of space above the table,
which is otherwise a bit too much for my liking.


By the way, your use of upright text for descriptive words in subscripts
is laudable — most people get this wrong.

However not sure why you chose to use \operatorname .
It is sufficient to use \mathrm or \text ; viz.

     \newcommand\cin{c_{\mathrm{in}}}

     \newcommand\cin{c_{\text{in}}}

which doesn't carry the connotation of the subscript being a math operator.
For example, conversion of your coding into MathML would do something 
undesirable here.

 \text is probably better to adopt generally, since it respects spaces 
between words.
viz.
     \newcommand\cin{c_{\text{in order}}}
