(230−108, 230, 260)-Net in Base 2 — Upper bound on s

There is no (122, 230, 261)-net in base 2, because

extracting embedded orthogonal array [i] would yield OA(2²³⁰, 261, S₂, 108), but
- the linear programming bound shows that MÂ â‰¥ 2423 906907 580468 277479 349413 556067 053430 053216 032374 525434 104378 793213 098031 316992 / 1 326150 802185 > 2²³⁰ [i]
