EXAMPLE
As irregular triangle:
1;
3, 6;
7, 11, 14, 25, 56;
...
The A030222(3) = 5 3-polyplets are oriented as follows to obtain their binary codes (see A246521):
. . . . . . . . . . . . 5 . .
2 . . . . . 2 . . . 4 . . 4 .
0 1 . 0 1 3 . 1 3 0 . 3 . . 3
This gives the binary codes 2^0+2^1+2^2 = 7, 2^0+2^1+2^3 = 11, 2^1+2^2+2^3 = 14, 2^0+2^3+2^4 = 25, and 2^3+2^4+2^5 = 56, respectively.
