Hi Nathann,

I guess this one needs also needs to be rebased on #16286 (that is a dependency of #16235).

  • Dependencies changed from #16235 to #16241
  • Status changed from needs_work to needs_review

Nonono actually this one is above #16241

Replying to ncohen:

Nonono actually this one is above #16241

Anyway, there is some rebase to do as there are some merging conflict with #16241.

Hi Nathann,

Don't you have better reference rather than "given by Brendan McKay"?

I thought that we moved TD6_12 from orthogonal_arrays to database... what happend?

Vincent

comment:16 in reply to: ↑ 15 ; follow-up: Changed 7 years ago by ncohen

Yo !

Don't you have better reference rather than "given by Brendan McKay"?

Well.... I sent him an email, he gave me the matrices .... :-P

I thought that we moved TD6_12 from orthogonal_arrays to database... what happend?

Yeah I thought I did too... Perhaps one of the conflicts, who knows ? :-D

Anyway the good news is that we did not end up with a weird situation where it has not been moved WHILE some code is trying to load it from database.py. At least it works. Well, we will fix that in a later patch. I hope that Volker will release the next beta soon, because right now the Design code is a bit "foggy". It exists as a set of differences on several trac tickets, but I would like to have it in Sage and be sure that there are no conflicts anymore :-D
