Gilbertâ€“VarÅ¡amov bound [i]

(152, 237, 13260)-Net in Base 4 — Upper bound on s

There is no (152, 237, 13261)-net in base 4, because

1 times m-reduction [i] would yield (152, 236, 13261)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12216 978389 905679 890580 400843 655659 332169 269792 691952 705657 379665 309680 256238 309929 498201 303301 458461 793395 289207 698761 827670 419445 112349 185220 > 4²³⁶ [i]
