(21, 87, 2641)-Net in Base 25 — Upper bound on s

There is no (21, 87, 2642)-net in base 25, because

the generalized Rao bound for nets shows that 25^mÂ â‰¥ 42 254539 581340 750356 153423 190081 740836 945598 370055 950195 086802 872169 540651 867912 838053 019188 624878 592975 960306 520923 503025 > 25⁸⁷ [i]
