The main functions provided are:

1. p = GRPfys(n); generates a random permutation of length n.

2. p = GRPmex(n); generates a random permutation of length n.

3. p = GRDrej(n); generates a derangement of length n.

4. p = GRDmex(n); generates a derangement of length n.

5. p = GRDMPP(p); generates a derangement of length n.

6. p = GRPcyc(p); generates a cyclic permutation of length n.

7. Various interrogation functions, e.g., IsCyc(p).

Included is a set of notes on Random Permutations and their implementation and testing.
