To a projective variety X one can associate Bir(X), its group of birational transformations. In this talk we will look at the question, how one can embed Bir(P^n) into groups of birational transformations in higher dimensions.
In particular, I will describe geometrical properties of an example of an embedding of Bir(P^2) into Bir(P^5) by Gizatullin and I will give a classification of certain embeddings of Bir(P^n) into Bir(X), where X is a variety of dimension n+1.
