(235−144, 235, 792)-Net in Base 4 — Upper bound on s

There is no (91, 235, 793)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3307 525827 849678 443690 897513 157153 247170 953200 257485 711888 666875 468621 207381 559907 379278 423325 969976 289540 101386 743965 649548 737853 681243 537500 > 4²³⁵ [i]
