WebThe first mapping is the mapping dictated by the permutation on the right. If a ↦ b on the right, then we need to see what element b maps to on the left: Let's say b ↦ c as determined by the permutation on the left. Then the mapping of a given by the composition of the permutations is given by

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 11, 2024 · 20. RDKGames. Non-cyclic groups can have cyclic subgroups with their own generators. DFranklin. As a point of terminology, if an element x doesn't generate the whole group G, then x is not a generator (for G). But yes, in that case g will generate a cyclic subgroup of G. Note also that even in a cyclic group, not every element x will generate ...
