This question is, in a way, a follow-up of this earlier question of mine.
Let $A$, $B$ and $F$ be finite groups and let $\alpha: A \to F$ and $\beta: B \to F$ be surjective homomorphisms.
Let $A \times_F B$ denote the fibered product of $A$ and... | {"url":"http://mathoverflow.net/questions/31783/isomorphism-type-of-fibered-products-of-groups/32040","timestamp":"2014-04-16T13:54:56Z","content_type":null,"content_length":"62514","record_id":"<urn:uuid:85359fe4-0b2d-4d66-98cc-7a82ca578aca>","cc-path":"CC-MAIN-2014-15/segments/1397609523429.20/warc/CC-MAIN-2014041600... |
