(122, 246, 1902)-Net in Base 4 — Upper bound on s

There is no (122, 246, 1903)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13070 179595 650771 895344 610015 309230 142839 112977 464610 116103 936819 610533 745596 394114 069390 344427 354112 873747 145178 073369 174248 181958 149294 138949 328740 > 4²⁴⁶ [i]
