(112, 112+108, 1938)-Net in Base 4 — Upper bound on s

There is no (112, 220, 1939)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2 871484 188720 914523 412112 988792 550392 661070 473010 984694 549325 918149 468731 136160 076715 526813 598210 603343 863712 309012 078684 535922 136352 > 4²²⁰ [i]
