(177, 177+68, 98311)-Net in Base 4 — Upper bound on s

There is no (177, 245, 98312)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3197 124225 879514 209434 525939 689335 711016 428540 012121 834649 611420 160256 423558 825062 294886 387252 195546 865993 637313 621500 680443 774090 367261 189803 320320 > 4²⁴⁵ [i]
