I'll need something like this: n=.'abcdefgabcdefgabcdefgabcdefgabcdefgabcdefg'
nc=.n="1 |:n,.(1|.n),.(2|.n),.(3|.n),.(4|.n),.(5|.n),.(6|.n),.(7|.n),.(8|.n),.(9|.n),.(10|.n) +/"1 nc 42 0 0 0 0 0 0 42 0 0 0 So it is clear, n repeats every 8 digits. There's got to be a non-looping way to define nc more concisely.
