Oh right, I think i understand now! So am I right in saying then that for every transposition σ=σ^-1?
So for my question, σ=(13)(254) but can i also say that σ=(13)(25)(54)(42)? Therefore σ would be equal to its inverse?
Hi :)
Is it right to say that for your given example that,
σ=(12)=σ^-1
When σ=(1234), I know that σ^-1=(1432). But I am unsure what permutation holds for σ=σ^-1.
Let n ∈ N. Explain what is meant by saying that π is a permutation of n = {1, 2, . . . , n}.
The permutation A is given below in two line notation. Write A in disjoint cycle notation.
1 2 3 4 5
3 5 1 2 4
Find A^-1, writing your answer in disjoint cycle notation. Give two examples of...
