The following information is available for U_{4}(5):

Standard generators of U_{4}(5) are **a** and **b** where
**a** is in class 2A, **b** is in class 4B and **ab** has order 9.

Standard generators of 2.U_{4}(5) = SU_{4}(5) are
preimages **A** and **B** where **AB** has order 9.

- Find an element of order 8, 24 or 60 and power it up to give
an element
*x*in class 2A and an element*t*in class 4B. - Look for a conjugate
*y*of*t*such that*xy*has order 9. - The elements
*x*and*y*are standard generators.

- Some primitive permutation representations.
