  We introduce a characterisation scheme for a universal qutrit gate set.
Motivated by the rising interest in qutrit systems, we apply our criteria to
establish that our hyperdihedral group underpins a scheme to characterise the
performance of a qutrit T gate. Our resulting qutrit scheme is feasible, as it
requires resources and data analysis techniques similar to resources employed
for qutrit Clifford randomised benchmarking. Combining our T gate benchmarking
procedure for qutrits with known qutrit Clifford-gate benchmarking enables
complete characterisation of a universal qutrit gate set.
