(31, 31+50, 24701)-Net in Base 32 — Upper bound on s

There is no (31, 81, 24702)-net in base 32, because

the generalized Rao bound for nets shows that 32^mÂ â‰¥ 82 665894 727193 713007 518736 334275 794104 874793 532744 592581 937094 574140 206336 990898 548925 476615 509575 904761 679982 345756 521095 > 32⁸¹ [i]
