    - Proof of New Implicational Relationships between Generalized Symmetries
    Neil Kettle and Andy King
    Technical Report 13-05, Computing Laboratory, University of Kent, Canterbury, Kent, CT2 7NF.
    Abstract: This note provides proof of some new implicational relationships between generalized symmetries. These relationships are formulated in terms of twelve symmetry types. Six of these symmetries are denoted (unknown variable T_){n}^{x_i,x_j}$ where the index (unknown variable n)in[1,6]$ indicates that a specific co-factor equivalence property holds between the variables (unknown variable x_i)$ and (unknown variable x_j)$. The other six symmetries are denoted $ eg T_{n}^{x_i,x_j}$, and indicate that one co-factor is equivalent to the negation of the other. The relationships that are specified take the form, if (unknown variable T_){p}^{x_i,x_j}$ and (unknown variable T_){q}^{x_j,x_k}$ hold then (unknown variable T_){r}^{x_i,x_j}$ holds where (unknown variable T_){p},T_{q}$ and (unknown variable T_){r}$ denote one of these twelve symmetry types.
