    Prism Permutations

    Hi!

    I have been trying to solve this problem for the past three evenings and I cannot understand the notation.
    'Describe geometrically the symmetries of the prism represented in cycle form by permutations (14)(23) and (25).

    The problem I have is to understand whether it is one permutation or a composition of permutations, so firs (14)(23) would be a reflection in the horizontal plane and then turned by pi/3. but what is confusing for me is that number 2 is here twice, so I am assuming it is a composition. Pleas advise if you can.

    ______
    l\ 1 /l
    l \ / l - back 5
    l 2|3|
    \ l /
    \ l / \ base 4
