Three colors to paint each side of a square, how many different squares?

Click For Summary

Homework Help Overview

The problem involves determining the number of distinct ways to paint the sides of a square using three different colors, considering that rotated versions of the same color arrangement are not counted as different.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the total number of color combinations and whether to account for rotations. There is a mention of using combinations with repetition and the potential need for permutations.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of how to count the arrangements. Some guidance has been offered regarding the consideration of rotations, and there is a suggestion to check combinations and permutations.

Contextual Notes

There is uncertainty about whether the order of colors matters and how to handle the counting of rotated squares. The original poster's initial calculation raises questions about the validity of subtracting one from the total combinations.

Homework Statement



If you have a square and can paint each side with one of three different colours, how many completely different arrays can you get? (rotated squares don't count)

Homework Equations


The Attempt at a Solution



I was thinking 3^4 / 4 but, that is not an integer, (3^4 - 1) / 4 is an integer but why would you substract 1?

You just have 4 edges of the square that you can colour? and does the order of the colours matter?
 
You might also want to consider if the same square rotated would counted as the same:
in other words would red, black, green, black be the same as black, red, black, green or different (both starting at the top of the square and going clockwise)?

I think my link will give you the information you need to solve it. I got an answer that I checked quickly by writing out all of the combinations.

Thanks. I thought we needed a permutation.
 
We actually need permutations and the answer should be around 24. I'm still looking for a solution.
