**Hint:** Get out some square sheets of paper and try to replicate the design.

**Solution Commentary:** On his web site, Graeme McRae shares this reasoning:

B, G, H, and A were all placed in corners.

C and F both cover B, and C covers F, so the order of this trio is B, F, C.

E covers G, so the order of this pair is G, E. Moreover, G and E both cover C, so the order of all the sheets visible on the left side must have been B, F, C, G, E.

D covers H, so the order of this pair is H, D. Also, both H and D cover E, so the order of the sheets must be B, F, C, G, E, H, D, A.
