We classify all compact 1-connected manifolds $M^n$ for $2 \leq n leq 7$ which are
di ffeomorphic to biquotients. Further, given that $M$ is di ffeomorphic to a biquotient,
we classify the biquotients it is diff eomorphic to. Finally, we show the homogeneous
space $Sp(3)\Sp(1) \tines Sp(1)$ and two of its quotients $Sp(3)\Sp(1) \times Sp(1) \times S^1$ and
$\delta S^1 \backslash Sp(3)/Sp(1)\times Sp(1)$ admit metrics of almost positive curvature.
