Don't worry:
You don't have to understand where the name comes from.
Without any further words.

They look amazing! Greatness!

Can you explain the name anyways?

Great work.

Does the puzzle on the left remind you of Optimus Prime?

Haha.

They both look great. I prefer the extended version over the normal version.

Would a Gyrobifastigium also be a member of the series? If not, I think you should make one anyway!

both looking beautiful, great job

Very nice and unique Andreas.

I am always amazed how consequently you follow the rules to build puzzles to complete logical sequences. My respect!

Thanks to all of you.

and enter the signature (obviously on the 3x3x3) and you should understand. No. It isn't. I think I will explain the reasoning behind the series after I finished it, whenever that will be. But maybe someone has already got it?
And I don't intend to start with the Johnson solids. The Catalans first. And the remaining Archimedian. Cursed thing!

Unique puzzle... I don't completely understand it....
