Query: Diameter of $SU_2$ for a left-invariant axisymmetric Riemannian metric   We consider the Lie group $SU_2$ endowed with a left-invariant axisymmetric
Riemannian metric. This means that a metric has eigenvalues $I_1 = I_2, I_3 >
0$. We give an explicit formula for the diameter of such metric. Other words,
we compute the diameter of Berger's sphere.
