Hi Nathann, I'm trying to work on a better class hierarchy for designs in sage right now actually. (Group divisible designs? _colored_ group divisible designs? t-wise balanced designs? Any of the other chapters/sections in the CRC? and why is the hadamard matricies/latin squares code separated? )
As far as the design package, I found the code very readable and approachable (with loop invariants commented even): <gap_root>/pkg/design/lib/blockdesign.g Also, on top of citing GAP, papers I read in the area use Discreta as well On the schedule for me later this summer is figuring out how to wrap the functionality of it without all the GUI code. http://www.mathe2.uni-bayreuth.de/discreta/ Anyway, if something like this is *already* broken by default, using something like rob suggested from graph theory for groups the other day is not a bad thing for designs: d = designs.<tab> On Fri, Jun 4, 2010 at 6:02 AM, Nathann Cohen <[email protected]> wrote: > Which..... may be caused by the fact I don't even know about Gap's > design package, which is required for this function ^^; >From sagenb.org in gap mode: LoadPackage("Design"); fail If you have not figured out already, a simple work around would be to install the design package in the normal pkg folder in the gap subfolder. As design is one of the standard packages, I believe this is done in sage by typing sage -i gap-packages, if not the site is here: http://www.gap-system.org/Packages/design.html Then doing sage -gap LoadPackage("Design"); ?WittDesign will show you Show you documentation for WittDesign. > > Nathann > > -- > To post to this group, send an email to [email protected] > To unsubscribe from this group, send an email to > [email protected] > For more options, visit this group at > http://groups.google.com/group/sage-devel > URL: http://www.sagemath.org > -- To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
