Is there a comma between y0 and z0?

It makes no difference.

Having any problems?

What about Ubuntu?

Ah, yes, sorry.

Unrelated to the topic, have you gotten around to looking at Elaina's problems yet?

Brilliant!

Now, what did you use to draw that cube?

Found it on the interwebs.

There isn't such an algorithm.

Consider the corners of the cube:

After each move, some of the odd labeled corners go into places of even labeled corners and vice versa. So, after any odd number of moves, odd corners end up in even numbered places and the even corners end up in odd numbered places, so such an algorithm is not possible.

Did you try any of thise? What did you get?

Abort works for me too.

There are still some problems that have persisted since 4.0.

Which problems?

I'm sure that if you post the proofs here someone will be able to respond.

The one you posted looks good (assuming I got what you meant to write; some parentheses are missing), but it generally depends what you assume you already know is true, like you said.

*are you

I'm a nerd, I would say. Which one do you think you are?

Hi harrychess

I'm getting 38 degrees.

Yep! It's interesting, to say the least.

The rest are not meaningless, just complex.

And, why not 10?

Isn't the transformation done on a matrix?

What are x and y?

Hi bobbym

See you later!

Thanks.

Here's the solution.

I think I figured it out. I will post it when I write it out.
