Abstract This paper studies the notion of quasiconformal homogeneity in various different settings - relative with respect to domains and ambiently. For instance we give an example of a compact set E which is homogeneous with respect to a quasiconformal family of maps of a domain containing E, but which is not quasiconformally homogeneous with respect to \mathbb{R}^n. We construct Cantor sets which are K--quasiconformally homogeneous for each K > 1 and explicitly identify their Hausdorff dimension, among other things.

Keywords quasiconformal, homogeneity, quasiconformal groups, Lie group.

Classification (MSC2000) Primary: 30C60.
