Comment:
Helloooooooo !!!
> I just have one query: given that the method is called BIBD_From_TD, I
was expecting the function to return a block design, but it returns a
list instead.
Hmmmm... Well, admittedly I do not like to wrap a list in a class if I
don't need to (because doing so may cost non-trivial computations), but in
this case the function is really only made to be called by the "main"
method, i.e. the constructor of BIBD. It can be called recursively, and it
would be nice if we don't convert all the stuff into a Block Design during
those calls as we have no reason to `^^;`
> You may set this to `positive review` if you would like to return a list
instead of a `BlockDesign`...
Thank you very much ! Now we are only one ticket away from having ALL bibd
with k=5, and I have another code ready on my computer : Wilson's
construction of MOLS with two truncated groups, which should make a big
difference in our table of MOLS. But that's for a bit later, for many
patches are still waiting to be merged and this is already sufficiently
complicated as it is. Pretty soon, I hope !!!
