        cyclic G &lt;=&gt; G is a cyclic group.                                   
    metacyclic G &lt;=&gt; G is a metacyclic group (i.e., a cyclic extension of a 
                     cyclic group).                                         
   generator G x &lt;=&gt; x is a generator of the (cyclic) group G.              
           Zpm x == the isomorphism mapping the additive group of integers  
                    mod # [x] to the cyclic group &lt; [x]&gt;.                     
      cyclem x n == the endomorphism y |-&gt; y ^+ n of &lt; [x]&gt;.                 
      Zp_unitm x == the isomorphism mapping the multiplicative group of the 
                    units of the ring of integers mod # [x] to the group of  
                    automorphisms of &lt; [x]&gt; (i.e., Aut &lt; [x]&gt;).               
                    Zp_unitm x maps u to cyclem x u.                        
    eltm dvd_y_x == the smallest morphism (with domain &lt; [x]&gt;) mapping x to  
                    y, given a proof dvd_y_x : # [y] %| # [x].                
   expg_invn G k == if coprime #|G| k, the inverse of exponent k in G.      
 Basic results for these notions, plus the classical result that any finite 
 group isomorphic to a subgroup of a field is cyclic, hence that Aut G is   
 cyclic when G is of prime order.
