Permutations group theory
WebApr 8, 2011 · The method I use for multiplying permutations like this is to think of each cycle as a set of mappings. a (in your example) maps 1 to 3, 3 to 5, 5 to 2, and 2 to 1. Also, remember that ab means "apply b, then apply a ." So, here, we want to see where ab maps each number 1-6. Start with 1: b fixes 1 (maps it to itself) and a maps 1 to 3. WebApr 27, 2024 · 1 I have a definition in my notes that states a transposition is a permutation which interchanges two symbols and leaves all the others fixed. Thus, if T is a transposition, then sgn ( T) = − 1. I understood transposition to be disjoint cycles of length 2. What does it mean when it says interchanges two symbols? group-theory finite-groups
