Gilbertâ€“VarÅ¡amov bound [i]

(203−76, 203, 8209)-Net in Base 4 — Upper bound on s

There is no (127, 203, 8210)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 165 793445 518021 236594 771849 450820 815135 196551 645863 331201 021946 041206 793772 532450 314362 584426 029105 930673 018859 757315 287040 > 4²⁰³ [i]
