I meant to add "and preserves the natural product measure on the set". Jim Propp On Saturday, September 12, 2015, Adam P. Goucher <apgoucher@gmx.com> wrote:
What's the nicest way to picture the product set S=DxDxDx... with D={0,1,2,...,8,9} as a subset of the reals so that lexicographic ordering of S is a restriction of the usual ordering of the reals?
f : (D x D x D x ...) --> R (d_0, d_1, d_2, ...) |--> sum(d_n / 11^n : n in {0, 1, 2, ...})
has the property you describe, unless I'm missing something.
