# Rubik's Cubes!

Everyone here should know about Rubik's Cubes. If not, you might not be prepared for this problem.

So the cube above is 1 of the 43 quintillion possible combinations for the cube. Look closely. You can see there are 2 stickers of the same color next to each other. In fact, in the picture, there are 4 of those blocks.

The question is "How many combinations are there that don't contain any of those blocks in any of the 6 faces of the cube? If there are none, what is the minimum number of blocks available?"

Looking forward to great solutions!

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
