  In 1885, Fedorov discovered that a convex domain can form a lattice tiling of
the Euclidean plane if and only if it is a parallelogram or a centrally
symmetric hexagon. It is known that there is no other convex domain which can
form two-, three- or four-fold translative tiling in the Euclidean plane, but
there are centrally symmetric convex octagons and decagons which can form
five-fold translative tilings. This paper characterizes all the convex domains
which can form five-fold translative tilings of the Euclidean plane.
