I want to read a book on group theory "Endliche Gruppen I" by Huppert, Blackburn etc. I do not know, whether it is translated in English. Can one suggest a way for this- "Online Mathematics dictionary, German to English", or whether book translated in English, or any other?
See this question. Here are two German-English mathematical dictionaries:
Offline there's a Langenschiedt English/German/French/Russian mathematical dictionary ISBN 3861170744, and Landau's Grundlagen der Analysis in the AMS edition comes with a "complete German-English vocabulary" that could be helpful. I don't think there is an English translation of Endliche Gruppen I.
