Last issue, number 22, was 9 years ago.

Marcus Goetz had the brilliant Thu, 16 Apr 2009 22:17:35 GMT discombobyoulater http://tech.groups.yahoo.com/group/polyforms/message/4571 http://tech.groups.yahoo.com/group/polyforms/message/4571 Thanks, that is a nice link. I would not call the diagonal cut parts "half cubes", since it would take four of them to make a cube. It appears that the basic Thu, 16 Apr 2009 09:30:54 GMT Bernd Karl Rennhak http://tech.groups.yahoo.com/group/polyforms/message/4570 http://tech.groups.yahoo.com/group/polyforms/message/4570 Hi Bob, to answer your question: I found a nice polyform puzzle on this web page: http://www.puzzlemochalovlp.com/ There is a set of twelve pieces from cubes Wed, 08 Apr 2009 07:21:51 GMT Esser http://tech.groups.yahoo.com/group/polyforms/message/4569 http://tech.groups.yahoo.com/group/polyforms/message/4569 Hi, some time ago I worked with diagonal cut cubes. Some sets and constructions are on my site http://mitglied.lycos.de/polyforms/ . I called the pieces Wed, 08 Apr 2009 05:04:58 GMT sterten@... http://tech.groups.yahoo.com/group/polyforms/message/4568 http://tech.groups.yahoo.com/group/polyforms/message/4568 compare this with Brendan Owen's generator, which should be in the files area. It's more flexible, new polyforms can be defined by a table and then generated.

Do you have some pictures of those somewhere? Thinking about this, there are many ways that one could define the allowable wedge (diagonal half-cube) Tue, 07 Apr 2009 23:50:43 GMT discombobyoulater http://tech.groups.yahoo.com/group/polyforms/message/4566 http://tech.groups.yahoo.com/group/polyforms/message/4566 It does not currently support diagonal half-cubes. This could be added, patterned after the classes for polycube and polytan. I'm not sure that I will have Tue, 07 Apr 2009 23:16:55 GMT Bernd Karl Rennhak http://tech.groups.yahoo.com/group/polyforms/message/4565 http://tech.groups.yahoo.com/group/polyforms/message/4565 Hi Is the generator able to work with half cubes (diagonal cut) ? And also fix numbers of mixed cubes and half cubes ? I have some of these polyform sets and Tue, 07 Apr 2009 21:33:46 GMT discombobyoulater http://tech.groups.yahoo.com/group/polyforms/message/4564 http://tech.groups.yahoo.com/group/polyforms/message/4564 Howdy, I've posted a new polyform generator in my files area in this group, polygen3.py. I intend this as a replacement for poly_gen.

I saw the image, but I didn't have the patience to count them! Bob H P.S. Very nice java solver applet.

Note that these do include those with holes in, but then so does the set of 206 hexacairoes. I used my polyform
