Mar 26, 2018 at 13:27 comment added Dominic van der Zypen Thanks for your comments and questions for clarifications -> I did mean translations and rotations, no axial symmetries.
Mar 26, 2018 at 10:35 comment added Joseph O'Rourke Whether or not a particular single polygon can tile the plane---a monohedral tiling---is not known to be undecidable. See "Is it decidable to determine if a given shape can tile the plane?."
Mar 26, 2018 at 10:29 comment added Peter Heinig Dear @Dominic: I proactively made some rather invasive changes. I think they improve the text. In particular, writing $T^{2n}$ seems unnecessary and even confusing to me, so I wrote $T(n)$. I also replaced 'copies' with 'translates'.

Several stylistic changes, which seem improvements to me. One substantive change: the ambiguous term 'copies' replaced with the defined term 'translate'.
Mar 26, 2018 at 9:54 comment added Sylvain JULIEN Actually I think the set of "copies" should form a group under composition of applications. So precising what this group is could help.
Mar 26, 2018 at 9:51 comment added Sylvain JULIEN Do you mean "translations and rotations" by "copies" ? Or do you allow axial symmetries too ?
