I let this simulation run further, and here are the results the next 
results:

Run size: 1024000
(474 of 10000 successful: 0.0474)
(Mean Steps: 471.88397)

This means that the network with 20 links undergoes a phase transition 
between 500 thousand and one million nodes, after which it doesn't work 
at all (this behavior isn't surprising). So if the network should grow 
to over half a million nodes, you definitely need more than 20 edges 
(and caching won't help).
