        OA with only one run / dual of code without redundancy [i]

(115−27, 115, 1908856)-Net in Base 5 — Upper bound on s

There is no (88, 115, 1908857)-net in base 5, because

1 times m-reduction [i] would yield (88, 114, 1908857)-net in base 5, but
- the generalized Rao bound for nets shows that 5^mÂ â‰¥ 48 148311 681413 889768 826845 459586 432045 646448 163570 138719 055593 812388 360571 262325 > 5¹¹⁴ [i]
