(245−162, 245, 619)-Net in Base 4 — Upper bound on s

There is no (83, 245, 620)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3589 720526 064366 990302 878467 240081 414754 776184 526598 593995 296777 011952 472673 093233 009360 716970 488478 845318 991375 105227 847236 310451 481250 341617 534158 > 4²⁴⁵ [i]
