Permutations of $(Z/pZ)^*$ Douglas Zare: thanks for the additional explanations, I should have included this when submitting the question... |

Permutations of $(Z/pZ)^*$ Joël: the question comes up rather naturally in a "recreational" but still serious project we're working on with Teo Banica and Ion Nechita, on complex Hadamard matrices. It looks like it might involves some ideas from basic number theory, things that I don't really know but that should be obvious to someone like you, so perhaps MO can help here... BTW, thanks for the editing. |

Permutations of $(Z/pZ)^*$ P Vanchinathan: yes, the - sign in condition (A) is the substraction in the ring $Z/pZ$ and your interpretation is correct. No, we do not assume that $a$ is a group homomorphism, just a map. |
