There is no (32, 226, 115)-net in base 4, because

extracting embedded OOA [i] would yield OOA(4²²⁶, 115, S₄, 2, 194), but
- the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 186070 713419 675363 980626 894819 329160 794532 188335 953423 432061 490990 243657 757029 868371 504908 982723 472783 555205 531204 141550 984858 016925 351936 / 13 > 4²²⁶ [i]
