The document discusses conjugate cyclic permutations in group theory. It defines a cyclic permutation τ as a bijection from a set of numbers n to itself, where it maps n to n and a number k to the number following it. It then defines the conjugate of a cyclic permutation τ by another cyclic permutation τ-1 as mapping the elements i1, i2, ..., ir of τ to their images under τ-1 in the same order. So the conjugate of τ by τ-1 is obtained by applying τ-1 to each element of τ.
