SUMMARY

This discussion centers on the assertion that no simplex possesses 2-fold symmetry. Participants express uncertainty regarding the proof of this claim and the methods for determining axes of symmetry in simplices. The conversation highlights the complexity of symmetry in geometric shapes, particularly when considering reflections through arbitrary points. It is established that most simplices exhibit reflection symmetry, such as through the midpoint of a 1-simplex.

PREREQUISITES
  • Understanding of simplex geometry
  • Familiarity with symmetry concepts in mathematics
  • Knowledge of reflection transformations
  • Basic grasp of geometric proofs
NEXT STEPS
  • Research geometric properties of simplices
  • Study reflection symmetry in higher-dimensional spaces
  • Explore methods for proving symmetry in geometric shapes
  • Investigate existing literature on axes of symmetry in simplices
USEFUL FOR

Mathematicians, geometry enthusiasts, and students studying geometric transformations and symmetry principles.

Heck, I don't even know if this is true. Intuition seems to suggest that it is but I know of no way to prove it. In general I don't know of any way to rigorously determine axes of symmetry. And I am having trouble finding anything about this, so any links are appreciated.

Is there something unclear/asinine about my question? I fear it may be a little vague.
 
It is a bit vague. If you allow reflections through arbitrary points, then most simplices have reflection symmetry. Ex: reflection through the midpoint of a 1-simplex. If you have something else in mind, then you should state it more clearly.
