Life Digits (2)

Posted in restricted patterns on July 9, 2009 by DIVVS·IVLIVS

Using the standard ‘life digits‘ these are the smallest numbers that can produce infinite growth for each base from 2 to 10:

Base 02: 16-digits: 0011001000100011
Base 03: 11-digits: 21011121122
Base 04: 10-digits: 0023321310
Base 05: 08-digits: 40101123
Base 06: 07-digits: 0253033
Base 07: 07-digits: 0051165
Base 08: 07-digits: 140732
Base 09: 07-digits: 140732
Base 10: 06-digits: 140732

Surprise! Dean Hickerson thought that the smallest number that produces infinite population growth was 154299. 😉
