Wir beobachten dass bestimmte Unteralgebren einer deformierten Fomin-Kirillov-Algebra eine enge Verwandschaft zu "kleineren" Fomin-Kirillov-Algebren besitzen. Wir benutzen diese Beobachtung um die Dimension (als Vektorraum) von Fomin-Kirillov-Algebren in einigen Beispielen, insbesondere für den vollständigen Graphen auf 5 Knoten, zu berechnen. Ferner untersuchen wir zu Fomin-Kirillov-Algebren zugeordnete Gruppen, die in einigen Beispielen eine sehr bemerkenswerte Struktur besitzen.

We observe that certain subalgebras of a deformed Fomin-Kirillov algebra closely resemble "smaller" Fomin-Kirillov algebras. This observation is used to calculate the vector space dimension of Fomin-Kirillov algebras in many examples, in particular for the complete graph on 5 vertices. Furthermore, we study groups attached to Fomin-Kirillov algebras. The attached groups turn out to posses striking structures in examples.
