<p>HeLP can detect that the character tables belong to the same group, if they are identical objects in GAP or if both are tables of the same group from the ATLAS and their InfoText begins with "origin: ATLAS of finite groups" (which is usually the case for ATLAS tables). If the program can verify that the character table which is used at the current call of a function belongs to the same group as in the previous call of a function, the solutions stored in <code class="keyw">HeLP_sol</code> are kept. If the character table belongs to another group or it can not be made sure that the character table belongs to the same group, <code class="keyw">HeLP_sol</
<p>Not reseting <code class="keyw">HeLP_sol</code> can also be achieved using <code class="func">HeLP_ChangeCharKeepSols</code> (<a href="chap3.html#X7BB9009482784E90"><span class="RefLink">3.4-1</span></a>). However, caution should be exercised when using this command since it may manipulate <code class="keyw">HeLP_sol</code> into something meaningless.</p>
