The 4-node loops should be generated by graph.isocreate(4, 8, directed=F).

> graph.isocreate(4, 8, directed=F)
Vertices: 4 
Edges: 4 
Directed: FALSE 
Edges:
          
[0] 1 -- 3
[1] 0 -- 3
[2] 1 -- 2
[3] 0 -- 2

Note that when you plot it with layout.circle, the result does not "look like" 
the 4-node loop, but it is nevertheless isomorphic to it.
