Abstract: We find formulas for the birational maps from a Kummer surface $ \mathcal {K}$ and its dual $ \mathcal {K}^*$ to their common minimal desingularization $ \mathcal {S}$. We show how the nodes of $ \mathcal {K}$ and $ \mathcal {K}^*$ blow up. Then we give a description of the group of linear automorphisms of $ \mathcal {S}$.
