Query: On the classification of toroidal compactifications with
  $3\bar{c}_{2}=\bar{c}^{2}_{1}$ and $\bar{c}_{2}=1$   We classify the smallest finite volume complex hyperbolic surfaces with cusps
which admit smooth toroidal compactifications and which are not birational to a
bi-elliptic surface. Remarkably, there is only one such surface which appears
to be the compactification of a Picard modular surface.
