Wikipedia's list of numeral systems lists only $10,20,60$ as having been used in history. There are about twenty-five sets of symbols there used by different groups of people, but only three different bases. I'm a little surprised that, even if some of these civilizations learned about positional notation from others and did not independently discover it, they changed up the symbols without exploring whether a different base could be used. I would have thought that base $30$ would be a decent candidate since it multiplies the first three primes (there are advantages with respect to the quantity of terminating rational numbers and convenient divisibility rules) while having only half the number of distinct symbols as $60,$ which has been used by Babylonians, and the number of days in a lunar month is 29-30 days (see Arabic calendar)
Question: Has there been a large group of people that worked with a base other than $10,20,60$ for day-to-day activities?
I have read this thread and it also mentions bases $10,20,60,$ but no other significant ones. There is a TED-Ed talk about on this subject as well, but it doesn't mention any others. excluding the usage of bases that are powers of $2$ for purposes related to computers.
