So, out of curiosity, I started toying around with the smallest possible
Lego-cube that is smooth on all sides. IE no studs, stud holes, technic pin
holes, etc showing on any of the 6 faces.

Getting a 6x6x6 stud cube wasn't too hard... a 5x5x5 was tricky, but doable, and
a 4x4x4 was similarly tricky but doable. But try as I might, I couldn't get a
smaller one.

So, challenge time: What's the smallest smooth cube you can build? And what's
the fewest pieces you can do it in? (My 4x4x4 cube took 23 pieces, although it
could be built flimsily with 21 pieces).

(...) I actually didn't think I would be able to do it but I stumbled upon this configuration for a 2x2, smooth cube with four pieces. (URL) Nathan (20 years ago, 27-Mar-04, to lugnet.build.schleim)

My challenge was even more challenging: building a die with smooth tiles on all six sides. You may have missed it when I announced it on Fri, 21 Nov 2003 (I didn't know there was a schleim-newsgroup). I started with a 9x9x9 die, very soon followed (...)
