What is the correct change of the following expression
alle Fakten, deren Auswirkungen und die ergriffenen Maßnahmen
into the genitive case
Beschreibung aller Fakten, der?? Auswirkungen und der ergriffenen Maßnahmen
I thought about derer but that is the genitive of the demonstrative plural pronoun die. So, what is the genitive of the demonstrative pronoun (die) in the genitive case (i.e. deren)? Is there a form? Does it simply stay unchanged (i.e. deren)? Or, is such an expression not possible at all?
Please consider dessen, too.
der Mann, dessen Haus und Hund
in genitive
ein Bild des Mannes, de??? Hauses und Hundes
