The laws of a Rubik's Cube

[xXdaveXsuperstarXx]

I used the search function and I think it would be helpful to make a thread like this. So I'll say what I know. *Please* no silly stuff, this is serious.

1. You can only flip an even amount of edges.

2. You can never flip 2,4,5,7, or 8 corners in the same direction.

3. You can only do an even amount of swaps.

4. You can only cycle an odd amount of pieces.

5. You can't flip a single corner

Um, I think I got all of them. Is there any more that I'm forgetting?

Quite flawed. Just take this: http://www.ryanheise.com/cube/cube_laws.html

 

[xXdaveXsuperstarXx]

Hm. I wrote down things that seem impossible on my cube.

 

[Stefan]

Here's one hint: You forgot the following law:

You can never flip 4 corners in the same direction.

Here's one hint: You forgot the following law:

You can never flip 4 corners in the same direction.

Sune/Anti-Sune + U-Perm from that position = 1 corner flipped

 

[Stefan]

Sune/Anti-Sune + U-Perm from that position = 1 corner flipped

Huh?

 

[xXdaveXsuperstarXx]

You can never flip 4 corners in the same direction.

Oh, so it should should be you can never flip an even amount of corners in the same direction?

 

[watermelon]

You can never flip 4 corners in the same direction.

Oh, so it should should be you can never flip an even amount of corners in the same direction?

If you do a Sune on U, then a Sune on D, you have rotated 6 corners in the same direction.

 

[xXdaveXsuperstarXx]

Okay, I fixed that. Still something wrong?

 

[Stefan]

Okay, I fixed that. Still something wrong?

Yeah. Your approach.

Another hint: You forgot this rule:

You can never flip 5 corners in the same direction.

Okay, I fixed that. Still something wrong?

Yeah. Your approach.

Another hint: You forgot this rule:

You can never flip 5 corners in the same direction.

Wait, i think i have the rule. You cannot flip an amount of corners in the same direction unless the amount is divisible by 3.

 

[Stefan]

Now that Waffle did it, too, it's pissing me off too much.

[xXdaveXsuperstarXx]

Yeah, so if you multiply that number buy 2, if it's legal it should be divisible by 3. So if you multiply 2, 4, or 5 by 2 it won't be divisible by 3.

it's my minion, not me
just to clarify on things, I'm not into the laws of cubes

 

[Stefan]

2. You can never flip 2,4,5, or 7 corners in the same direction.

Wow. You forgot 8.

 

[xXdaveXsuperstarXx]

At least I got the right equation.

 

[Stefan]

Hint: You forgot this law:

You can never flip 2 corners in the same direction and 1 in the other direction.

 

[elcarc]

easiest rule.

its impossible to get sub 3 sec unprepared solve. humans just dont move fast enough

 

[xXdaveXsuperstarXx]

Okay, so let me guess, you can never flip 2,4,5,7,8 corners in the same direction and flip 1 corner in another direction.

Yet. Thinking like that will get us nowhere. The sky's the limit!
