Probably the most general approach to tiling doesn't use boxing at all, but uses indexing. For example: seed=: p:i.3 3 target=: i.10 10 (,seed){~($seed)#.($seed)|"1 ($target)#:i.$target 2 3 5 2 3 5 2 3 5 2 7 11 13 7 11 13 7 11 13 7 17 19 23 17 19 23 17 19 23 17 2 3 5 2 3 5 2 3 5 2 7 11 13 7 11 13 7 11 13 7 17 19 23 17 19 23 17 19 23 17 2 3 5 2 3 5 2 3 5 2 7 11 13 7 11 13 7 11 13 7 17 19 23 17 19 23 17 19 23 17 2 3 5 2 3 5 2 3 5 2 > Also is there a way to unbox and have this retain its current structure?
