For some representations of the hypercubic group commonly used in simulations we define the sets of possible mixing operators and compute the one-loop mixing matrices of renormalisation factors. Tadpole improvement is applied to the results and some numerical examples are presented.8 pages, 2 figures, Talk given at Workshop on Computational Hadron Physics, Nicosia, September 2005High Energy Physics - Latticetext
