comment Is there a continuous bijection between an interval and a square: $[0,1] \mapsto [0,1] \times [0,1]$?
@copper.hat Your answer shows an other side of the die. Please let it live.

@BobPego The bijection requirement was a first instinct. You made me realized I can forgo it. Thank you for your insightfull comment.

comment Show that, for a random walk $X$ on $\mathbb Z_2$, $X_\infty$ is independent of the past $\left\{ X_t \right\}_{0\le t<\infty}$
By 'coincides', you mean in distribution: if $X$ is a random walk on $\mathbb Z_2$, as above, and $\left(Y_t\right)$ is an i.i.d sequence with uniform distribution on $\mathbb Z_2$. Then $X_t \buildrel{d}\over = Y_t, \forall t$. I don't see a proof for a stronger mode of convergence.
