Hi,
this puzzle is obviously a simple truncation of a 3x3x3.
I made it because it fills another empty slot I wasn't aware of until some month ago.
There are 33 subgroups of the symmetry group of the hexahedron, including the two trivial subgroups. I scanned through my collection and found that I already owned 21 of these. Most of the missing ones are rather unsymmetric and near to the no-symmetry.
I built this new puzzle just to fill this once-empty slot.
BTW: Another slot was filled by Rafael Gulluni in the meantime.

What do you think?
Has anybody seen any other puzzle with this symmetry?

Beautiful!

Wow. Now that's a puzzle that can trick the eye... (It looks like something much cooler than just a 3x3)

Wonderful! Now, the extended version.

Andreas, this is my favorite of your truncation only 3x3 mods. Well done!!!!!!

Nice mod. I also love truncations.

Very beautiful puzzle! This is one of the cooest shape mods I've seen, especially of just 3x3x3.

Keep up the great work!
