Determining isomorphic summetry groups
Posted on 2011-03-17
I have three shapes, the group for each shape is a symmetry group. I need to determine which two groups are isomorphic.
The shapes are a triangle, a square, and a four pointed star (which is essentially a square with a triangle stuck on each side).
Visually the square and the four pointed star appear to be isomorphic, but how to I show this?
