(207−118, 207, 937)-Net in Base 4 — Upper bound on s

There is no (89, 207, 938)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 43745 949286 101505 138037 824120 319314 042217 577077 182890 344896 770051 259261 721695 048094 634947 544274 606006 202834 805573 308707 441600 > 4²⁰⁷ [i]
