 Standard group notions and constructions based on the prime decomposition  
 of the order of the group or its elements:                                 
        pi.-group G &lt;=&gt; G is a pi-group, i.e., pi.-nat #|G|.                
<ul class="doclist">
<li>&gt; Recall that here and in the sequel pi can be a single prime p.

<ul class="doclist">
<li>&gt; This is provided mostly as a shorhand, with few associated lemmas.   
       However, we do establish some results on maximal pi-subgroups.       
          pi.-elt x &lt;=&gt; x is a pi-element.

             x.`<i>pi == the pi-constituent of x: the (unique) pi-element     
                       y \in &lt; [x]&gt; such that x * y^-1 is a pi'-element.     
      pi.-Hall(G) H &lt;=&gt; H is a Hall pi-subgroup of G.                       
                    := [&amp;&amp; H \subset G, pi.-group H &amp; pi^'.-nat #|G : H| ].

      p.-Sylow(G) P &lt;=&gt; P is a Sylow p-subgroup of G.                       

</li>
<li>&gt; This is the display and preferred input notation for p.-Hall(G) P.   
          'Syl_p(G) == the set of the p-Sylow subgroups of G.

 Note that notions are always defined on sets even though their name        
 indicates "group" properties; the actual definition of the notion never    
 tests for the group property, since this property will always be provided  
 by a (canonical) group structure. Similarly, p-group properties assume     
 without test that p is a prime.
