(124, 124+128, 1878)-Net in Base 4 — Upper bound on s

There is no (124, 252, 1879)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 53 280715 400958 508360 664230 032645 505148 621502 189685 303801 125570 736971 913196 879033 816066 257064 177676 484654 862208 934567 739159 953706 247059 952581 236891 836769 > 4²⁵² [i]
