(92, 92+128, 913)-Net in Base 4 — Upper bound on s

There is no (92, 220, 914)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2 910600 857014 337329 895485 248551 102601 334249 561598 297196 866740 702574 329522 728510 238533 981286 383681 444309 204368 243401 764156 449227 818130 > 4²²⁰ [i]
