There are 248,540,275,292 different 3X3X3 3-piece burr assemblies. The highest solution level is eight, and there are eighty such solutions. Of these, three have only nine internal voids. This is one of them.
The eighty solutions come apart in essentially two different ways. Of the three solutions with only nine internal voids, one comes apart one way and the other two come apart the second way. Giga Burr comes apart the first way, while Giga Burr 2 comes apart the second.
