Linear OOA(7^m, (m+n)/2, F₇, 2, k) with arbitrarily large values for k and n such that n mod 2 = 1, provided that m is sufficiently large, using 7¹ times duplication based on linear OOA(7^m, (m+n)/2, F₇, 2, k) with arbitrarily large values for k and n such that 2 divides n, provided that m is sufficiently large, using

• repeating each code word k+1 times [i] based on linear OOA(7⁰, s, F₇, 2, 0) for arbitrarily large s, using
  • OOA with only one run / dual of NRT-code without redundancy [i]
