Returns TRUE if two permutations are conjugate and FALSE
otherwise.
Usage
are_conjugate(x, y)
are_conjugate_single(a,b)
Arguments
x,y,a,b
Objects of class permutation, coerced to cycle form
Value
Returns a vector of Booleans
Details
Two permutations are conjugate if and only if they have the same shape.
Function are_conjugate() is vectorized and user-friendly;
function are_conjugate_single() is lower-level and operates
only on length-one permutations.
The reason that are_conjugate_single() is a separate function
and not bundled inside are_conjugate() is that dealing with the
identity permutation is a pain in the arse.
