minus-squareMalgas ( Malgas@beehaw.org ) linkfedilinkEnglisharrow-up23·10 个月前4.2 billion from 4 dials would require ~256 positions per dial, which these don’t appear to have anywhere near that many markings. It looks to me like each of the four is actually two dials stacked atop one another. And eight 16-position dials is also 4.2 billion.
