Finally got it ! Sending the solution via the webbrowser did not work. I think the number is
much to long to send via 'GET'. I don't know if the browser is the Problem but sending it via
POST ( and a small java-programm ) did work.
BTW : I dont know if this number is REALLY prime - but my solution was ' prime enough '
I was sure I had a script capable of dealing with all the possible subsequences of a limited portion of pi... but it doesn't. I rote it in Python, can I PM someone to let him/her control my script?
