we are already building `GQ(q,q)` and `GQ(q,q^2)`; this ticket will give
`GQ(q^2,q)` and `GQ(q^2,q^3)`. So we will need `GQ(q^3,q^2)` - I can do
this on this ticket too, as
this is essentially a small modification:
- I build points and lines of the `GQ(q^2,q^3)`, and use them to create
the graph;
- I can also use them to create the intersection graph of the lines,
which will give the graph of `GQ(q^3,q^2)`.
What remains is `GQ(q-1,q+1)` and its dual, `GQ(q+1,q-1)`.
