(27, 27+38, 335074)-Net in Base 81 — Upper bound on s

There is no (27, 65, 335075)-net in base 81, because

the generalized Rao bound for nets shows that 81^mÂ â‰¥ 11260 070507 294409 954446 473925 305658 508750 980813 535545 355440 513590 227727 898727 067208 381145 202384 484001 897921 251016 699087 554001 > 81⁶⁵ [i]
