  This paper uses results on the classification of minimal triangulations of
3-manifolds to produce additional results, using covering spaces. Using
previous work on minimal triangulations of lens spaces, it is shown that the
lens space $L(4k, 2k-1)$ and the generalised quaternionic space $S^3/Q_{4k}$
have complexity $k,$ where $k\ge 2.$ Moreover, it is shown that their minimal
triangulations are unique.
