Description (last modified by )
With this branch we have a MOLS_table
function which displays what Sage can handle, and also compare it with what the Handbook of Combinatorial Designs (2ed) claims.
We seem to be rather far but I have several construction that somehow make the gap smaller. But there is a lot to review already :P

Indeed, a lot of minus... but at least two pluses!

Don't worry about the minuses... They are an endangered species.

Hi Nathann,
In u/vdelecroix/16423 I simplified some of the string formatting and aligned the Handbook table. If you are happy with it, set to positive review.
Vincent
comment:6 Changed 5 years ago by
I align a part of the alignment. Aaaaaaaaand set the ticket to positive review hoping that you will have nothing against it :P
Nathan
P.S. : and now that this branch is positvely reviewed I will have to rebase all other branches above it, as they will all conflict with the new MOLS table.....

Okay, let's do it the other way around otherwise it will be a mess....

Hi,
I did the rebase over #16347 at public/16423
. It looks good to me, just do a double check.
