hello!!
Would you mind giving more details about an algorithm in maple to find the set of involution defined by I (n): = {L in S_n such that L ^ (- 1) = L} (with S_n the set of permutations of {1..n} in {1..n}) ie for example I (2) = {L in S_2 / L ^ (- 1) =
L} = {(1,2), (2,1)}.
thanks,
Marwa Abdelmaksoud.
