(160, 160+70, 41902)-Net in Base 4 — Upper bound on s

There is no (160, 230, 41903)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2 978399 200877 714664 539330 005865 334325 496501 714024 039445 805046 597594 146958 959088 568579 596134 118372 757558 362583 519848 693433 047610 844800 705832 > 4²³⁰ [i]
