(219−106, 219, 2067)-Net in Base 4 — Upper bound on s
There is no (113, 219, 2068)-net in base 4, because
- the generalized Rao bound for nets shows that 4m ≥ 720977 868262 414843 112145 349314 363051 404474 920367 265762 831063 331852 637322 572363 390832 015231 167607 264827 390659 847283 365129 023693 780480 > 4219 [i]
