I was exploring the kind of problem lately and ended up with:

   (,.97 98 99) (,2)}"1 i. 3 3

Left rank never occurred to me.

While we're playing with structures, is there a better way to unbox boxes
of arrays than the following:

   (2 2$2)<;._3 i.6 6
┌─────┬─────┬─────┐
│0 1  │2 3  │ 4  5│
│6 7  │8 9  │10 11│
├─────┼─────┼─────┤
│12 13│14 15│16 17│
│18 19│20 21│22 23│
├─────┼─────┼─────┤
│24 25│26 27│28 29│
│30 31│32 33│34 35│
└─────┴─────┴─────┘
   > ,.&.>/ ,&.>/ (2 2$2)<;._3 i.6 6
 0  1  2  3  4  5
 6  7  8  9 10 11
12 13 14 15 16 17
18 19 20 21 22 23
24 25 26 27 28 29
30 31 32 33 34 35

maybe a tesselation inverse?
