How many ways are there to arrange $6$ beads of distinct colors in a $2 \times 3$ grid if reflections and rotations are considered the same? (In other words, two arrangements are considered the same if I can rotate and/or reflect one arrangement to get the other. Assume that each square gets exactly one bead.)

Please refer to this programming solution from me: https://web2.0calc.com/questions/hlp_25#r2

I think your answer is too big Max ://

 

If the beads were just in a circle, where just rotations are the same then the answer woud be 5! = 120

But there are less options than this because of the reflection aspect.

 

As far as reflection goes, these 3 are the same

 

 

So I am thinking tht the answer might be  120/3  =  40

Glowlife,  if you are given an answer, maybe from your teacher, then please show us  (with the logic behind it if possible).
