Sticky Cantor sets ★★

Author(s):

Conjecture   Let $ C $ be a Cantor set embedded in $ \mathbb{R}^n $. Is there a self-homeomorphism $ f $ of $ \mathbb{R}^n $ for every $ \epsilon $ greater than $ 0 $ so that $ f $ moves every point by less than $ \epsilon $ and $ f(C) $ does not intersect $ C $? Such an embedded Cantor set for which no such $ f $ exists (for some $ \epsilon $) is called "sticky". For what dimensions $ n $ do sticky Cantor sets exist?
