21<p>An <a class="reference" href="./integral-sequence-wrapper.html">Integral Sequence Wrapper</a> is a class template that provides a concise
22interface for creating a corresponding sequence of <a class="reference" href="./integral-constant.html">Integral Constant</a>s. In
23particular, assuming that <tt class="literal"><span class="pre">seq</span></tt> is a name of the wrapper's underlying
24sequence and <em>c</em><sub>1</sub>,<em>c</em><sub>2</sub>,... <em>c</em><sub>n</sub> are integral constants of an integral type <tt class="literal"><span class="pre">T</span></tt> to
25be stored in the sequence, the wrapper provides us with the following
26notation:</p>
