Hi Nathann,
This is not clear (at least to me)
This is possible, because `PG(2,2)` is a subdesign in `PG(2,16)`; in a cyclic `PG(2,16)` or `BIBD(273,17,1)` the points `\equiv 0 \pmod{39}` form such a subdesign.
It would be better to have the (273,17,1) from the difference family constructor... I just did it and there is an extra check in the doc that it is actually a cyclic one: u/vdelecroix/16524
.

Ahahahah. It is "Julian Abel's truth". And as the constructions works... :)

I just pushed it to the branch, but in the future I guess that we will remove this function as we add the patch of all DF found in the handbook. We will not create a function for each of them, and it will be a dictionary ... Anyway !

I mean, what is a PG? what do you mean by points \equiv 0 \pmod{39}
?

Of course, it is on my todo list... but in the meantime let us continue the way we started!

\equiv 0 \pmod{39}

Oh ! Well, a projective plane ! PG = Projective Geometry. And the points congruent to = mod 39 are somehow "defined" as it is a cyclic design on 273 points.
Of course, it is on my todo list... but in the meantime let us continue the way we started!
Yepyep...

Hi,
More docs at u/vdelecroix/16524
. It is the only method where the notation PG
is used!! If you like, take it and set to positive review...

No conflict > no update needed. Stop making me work for nothing, or do it yourself.
