Yes, I think so.

Keep in mind that:

1) I'm not a mathematician, but a simple linux fan that works in an high
school
2) I report only the comments I hear. I do not know if they are
correct or not.

In any case I really apreciate the comments on the argument that I see in
this list and I would like to thank all the people that is wasting his/her
time for considering my (silly?) requests.

TIA
