(14, 73, 5636)-Net in Base 64 — Upper bound on s

There is no (14, 73, 5637)-net in base 64, because

1 times m-reduction [i] would yield (14, 72, 5637)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 11142 445719 324421 119838 310088 132211 941678 400381 332346 796563 356246 588283 088274 488693 603669 711043 793815 967807 735858 144942 607455 684096 > 64⁷² [i]
