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.
