I was been told that there is a grid of size 11x11 filled with
integers 0,...,9 such that one can read the squares of 1,...,100 from
the board. Here read means that you fix a starting square and the
direction (8 possibilities) and you can go to that direction as many
steps as you want. For example, in a grid

0 1 4
9 3 6

you can read the squares of numbers 1, 2, 3, 4, 6 and 8.

However, I can't find an example of such a grid. Can anyone give an
example?
