Hi,
welcome to the puzzle of the day.
Today I present just another systematically truncated and extended puzzle.

Take the
Corner Truncated 000 001
in the left half of the picture and extend four of the original pieces and you get
Corner Truncated 000 001 Extended
on the right.Not to myself:
I should stop making pyramids. They are way to difficult to store.

Interesting. What do the other sides look like and what are the available turns?

It's still just a 3x3x3. I think the back comes down to make a right triangle when viewed from the side, but I could be wrong.

Is there a specific way you bandage all of your puzzles?

They are not bandaged, they are just truncated and extended, meaning that only the original 3x3x3 turns are available.

This mod has indeed no more than 4 sides which are triangular.
I should mention that in this case the signature is not a bandaging signature. Here the number is nothing more than a way to mention the two truncated corners:
It is like a coordinate system. 000 is one corner. The opposite corner would be 111. The rest should be obvious.

Oops. I said it wrong.
