- I checked this out and found the Gelbaum book's problem, (number 8), does
- NOT ask for a homeomorphism, but for a continuous map from [0,1) onto R.
- `````````` ````
- This falls just short of being a homeomorphism, of course, as it need not be 1-1.
-
- The solution given stretches out [0,1) increasingly, and folds it to and fro
- onto R in ever-widening zig-zag fashion.
- Every point in R has infinitely many preimage points.
