(222−134, 222, 795)-Net in Base 4 — Upper bound on s

There is no (88, 222, 796)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 47 463808 661414 940689 322576 327990 435149 588421 757090 747054 068537 667968 611139 783933 424302 232468 441700 139087 465395 169606 785471 299473 693100 > 4²²² [i]
