REMARKS
 Groombridge 34 is the closest star system in the first octant,
but it is probably not a leading hub candidate for subsequent stellar destinations.
For one thing, a direct flight to Ross 248 is closer then direct to G..34;
thus, it makes more sense to make Ross 248 the hub and G..34 the subsequent. 
TE does just that in Octant IV as R..248 is the closest star in that octant.
