Which tetrahedron block can build it's larger self ?? Well here again Fuller's A-B-T-E-K modules CAN'T Zubeks modules YES THEY CAN. each every one can build it's larger self. But I also have realized this is not so unique as I thought, and the reason I thought this way because in years people were questioning me and they were surprised, of a giving block to build it's larger self, so I assumed it to be UNIQUE.
Now I even showed that the infamous A-B modules can build they larger self, if dissected cleverly if dissected by Fuller, well no they CAN'T do much of anything, which makes the problem now unique by it's inability to do so, because by one method ALL tetrahedrons can build they larger self accept A-B the way Fuller have derived them, they can't build they larger self, so it makes it unique.
