(202−128, 202, 602)-Net in Base 4 — Upper bound on s

There is no (74, 202, 603)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 43 731324 653499 891953 005403 499536 609376 382722 818750 351499 468341 374366 874812 886456 862970 443468 166659 952519 228609 959623 306701 > 4²⁰² [i]
