(243−112, 243, 2919)-Net in Base 4 — Upper bound on s

There is no (131, 243, 2920)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 203 066274 081131 507898 364896 197337 445965 104448 950760 684521 638151 770253 661778 446724 005332 452900 626405 227738 904477 981456 013835 697980 662726 976513 293720 > 4²⁴³ [i]
