(80, 80+144, 630)-Net in Base 4 — Upper bound on s

There is no (80, 224, 631)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 795 049020 394701 453127 906499 788830 162038 383042 885341 429418 118389 037958 823662 211295 948768 655529 262850 380985 770349 520231 003013 553306 934954 > 4²²⁴ [i]
