Spirit of 76 with no products (Posted on 2004-07-13) Difficulty: 3 of 5
Can you find a 76 digits multiple of 2^76, written exclusively with sixes and sevens (as asked in "Spirit of 76"), starting with the (given) value of 2^76, and doing nothing but a (relatively) few sums?

(To be more precise: you should be able to do this by hand, with just pencil and paper, in a reasonably short time -- minutes, not hours or days.)
