Digital (127, 215, 289)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(127, 127+88, 4995)-Net in Base 4 — Upper bound on s

There is no (127, 215, 4996)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2789 844040 888671 361814 470612 696070 910812 783550 160421 202851 544494 792972 635564 590469 798544 417172 444134 795628 449967 692758 959113 727136 > 4²¹⁵ [i]
