[modulo 7]

Please write some more terms of the "and so on". Won't be that random as
you seem to expect. Draw your conclusions.

I know it's not random.
But how do you compute c modulo 7 with c =sum(a_i)
where a_i are the digits of the numbre 3^1000?
It does'nt seem as straightforward as with c modulo 3.
I even wonder if it's possible to solve the problem.
