(236−128, 236, 647)-Net in Base 3 — Upper bound on s

There is no (108, 236, 648)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 41052 283272 332147 105035 093591 271047 083966 665669 895488 093961 370636 147447 845630 165171 773882 369383 939253 757851 566081 > 3²³⁶ [i]
