(123, 249, 1889)-Net in Base 4 — Upper bound on s

There is no (123, 249, 1890)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 819805 540007 729851 637392 037853 703979 896217 203971 777375 036444 149320 891211 318859 323838 707100 227028 615170 114900 175316 090818 597333 138094 338697 521133 160608 > 4²⁴⁹ [i]
