Let $M = w_0w_1... \in \{0,1\}^*$. For any computable function $f$ define $M_f = w_{f(0)}w_{f(1)}...$ Let for any computable function $f$ with infinitely range of values there is continuous computable mapping between $M_f$ and $M$ (we can reestablish $M$ by its any computable subsequence) Is it possible that $M$ is non-computable?
