I'm a PhD student at the Department of Mathematics, University of Toronto.

Previously I studied mathematics, physics and computer science at University of Warsaw, where I obtained M. Sc. degree in mathematics.

My main interests are geometric group theory and discrete probability. I'm also interested in theoretical computer science, combinatorics and theoretical physics.

comment Can a tree cover a finite graph with arbitrary large girth?
I don't see how the group $G$ enters the picture here.

Thanks for posting this, it's quicker and tidier than the explicit calculations I wrote down in my answer
