(21, 21+74, 2351)-Net in Base 25 — Upper bound on s

There is no (21, 95, 2352)-net in base 25, because

the generalized Rao bound for nets shows that 25^mÂ â‰¥ 6 382225 660369 924135 995562 840004 391379 457557 587525 963036 882994 181658 389513 130117 809884 202533 988956 038280 680193 219640 073858 437886 532225 > 25⁹⁵ [i]
