group theory
Groups are staples in mathematics and group theory is often described as the study of symmetry. But what does that mean? Find out with Justin Chen!
Trying to solve a Rubik's cube? A Cayley graph gives you a road map for doing this — and is similarly useful for dealing with any other type of mathematical group!
Groups have become a core part of the language of modern mathematics and theoretical physics. On this page, find out how groups can help describe roots of polynomials, holes on a surface, and even the laws of physics!
Group theory is the mathematics of symmetry and structure. On this page, find out what a group is and how to think about them.
What exactly do we mean when we say group theory is the study of symmetry? Group actions make precise what it means for a group to act by symmetries on an object.
We guide you through an exciting recent breakthrough in the world of topology, involving something called the telescope conjecture.
We continue our exploration of the telescope conjecture.
In this podcast mathematician Cheryl Praeger and magician Will Houstoun reveal the maths and magic behind shuffling cards.
Explore the mathematical study of symmetry with this collection of content, which includes short introductions, in-depth articles, a podcast, and some magic!
What is group theory and why is it such an exciting area of maths? Two experts explain.
When things go round and round, a cyclic group may be just what you need!
Groups occur all over mathematics, so it makes sense to find a common language to talk about them all.
