(106, 106+142, 1094)-Net in Base 4 — Upper bound on s

There is no (106, 248, 1095)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 210846 322482 254244 784823 497305 991457 512863 595170 510659 770328 708027 948846 405501 122219 165670 215525 432267 590845 152383 197130 462096 148566 724440 438280 527580 > 4²⁴⁸ [i]
