Well, thank you first at all^^

but somehow i dont understand this...it contains so many variables like u,m,n,k,l,N,T and now i am more than confused

could somebody explain it in easy language or just explain the variables?

and by the way what is 10^phi(m)? =) i thought it was the funktion which donates to every m the quantity of numbers throught which m cannot be devided.

so for m = 7 (phi(m)=6 (1,2,3,4,5,6) it would mean: 10^6 = 1 (mod n)

doesn't a mod n give u back the rest-number which results from a devided through n??

so 1 (mod n) = n always...? hum..??

and in this example it would mean: 10^6 = 7^^

something is wrong here

can u explain it to me?

thx =)
