Rotational symmetry of Isosahedron category 5:38
This is very nice and clear presentation In this presentation, you are able to address like 60% of group theory topics. This is very nice applied presentation.
Very intuitive. Very brilliant. I just couldn't stop watching. It would be nice to see what you could say about sylow theorems, and about real world applications of group theory in other fields of study, or every day life problems (engineering, cryptography, rubiks cube, etc).
That was actually a quite nice way to Illustrate this fact. To be Honert ist was nothing new, since its not to hard to prove the simplicity of A_5 algebraicaly. But its always nice to see your results properly illustrated.
Thank you so much for covering these things in an excellent way
I watch some video from your channel time to time just to reach inner balance and sense that everything is just perfect :)
Thanks so much for your sharing. Love your channel very much.
Thank you!! I needed that video for my math class
Wonderful Series I love it ❤️
I have a hw problem of representation of A5 and it was hard for me to visualize icosahedron. Thank you.
0:30 Orbit stabilizer
8:10 you can also merge the 72- and 144-degree rotations.
Very Excellent.
Fantastic
It would be fun to ask students to find classes and symmetries and then tell them that all the other answers they wrote are actually correct.

Excellent video. A doubt remains: are the symmetry groups of the faces, the edges and the vertices related somehow to the symmetry group of the icosahedron? I've learned with this video that they are not subgroups, but their symmetries are all among the symmetries of the icosahedron. If so, how to call this relationship? Or is this a property not of the groups themselves, but of the geometrical realization of it? Thanks
So you are saying that there is no general quintic???!!!
Is your native language Cantonese by any chance?
