Classification of the orientation preserving isometries of $\\mathbb{E}^4$.

Classification of the orientation preserving isometries of $\\mathbb{E}^4$. References I can\'t find a classification of the orientation preserving isometries of $\\mathbb{E}^4$. I found this e somewhere on the internet but of course it also raises the question of there being a general classification of the isometries of $\\mathbb{E}^4$. Does anyone know if this exists and willing to prove this as well? Thanks!
