Further testing.

- for number=100, we get results.
- for number=500, we aborded the calculation after approx 45 mins
  without result.
- ideas: first, giving a feedback about the state of computing and then,
  doing stuff parallel. maybe filling the matrix or simply calling
initW#().

Merged. Omega still needs to be fixed.
