What are some relationships between a matrix and its transpose? Could you please elaborate on what it explains? |

Applications of design theory @GerryMyerson: I did, but I could not find the kind of applications I was looking for. I need a more meta-view of how designs are applied. The book does not mention agriculture for example. |

Multiplicative group of integers modulo n @anon: Isn't the binary operation ordinary multiplication in the case of the cyclic group of order n being understood as the nth roots of unity? So the identity element should be $1$. If we interpret $U_n$ as a subgroup of the nth roots of unity, $1$ should be within $U_n$. If the binary operation is not ordinary multiplication then what is it? |

Multiplicative group of integers modulo n I think I understand. But why are you removing $1$? |

Multiplicative group of integers modulo n Thanks. A couple of things aren't clear to me. Firstly why is what you said a subgroup (there seems to be no identity, closure and inverse aren't clear either). Secondly, why is this the same as our traditional $U_n$? |

Showing that this set of functions is a group. In addition to the excellent answers below, I will add that this group is isomorphic to $S_3$. |
