(160, 240, 21496)-Net in Base 4 — Upper bound on s

There is no (160, 240, 21497)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 124757 791042 202370 065865 756796 866732 818584 024161 026165 372044 599147 194412 048578 997898 142233 830935 407993 067164 336707 870828 606419 981710 139969 046571 > 4²⁴⁰ [i]
