(202−120, 202, 774)-Net in Base 4 — Upper bound on s

There is no (82, 202, 775)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 44 023434 177161 250989 488221 514712 759401 833795 693753 871742 718630 784961 758374 578691 070018 541543 792245 346679 965387 232775 463776 > 4²⁰² [i]
