+\k{FreeNet}, written by Pavils Jurjans; there are several other
+implementations under the name \i{NetWalk}. The computer prepares a
 network by connecting up the centres of squares in a grid, and then
 shuffles the network by rotating every tile randomly. Your job is to
 rotate it all back into place. The successful solution will be an
-entirely connected network, with no closed loops. \#{Is it also true
-that a correct solution will not contain any cycles?} As a visual aid,
+entirely connected network, with no closed loops. \#{The latter

+Could this be clearer? "No closed paths"?} As a visual aid,
 all tiles which are connected to the one in the middle are
 highlighted.
