    Which is why it feels kind of prime, imho. I don’t know if other people get this, but I get a sense of which two-digit numbers are prime probably because of how often they show up in times tables and other maths operations.

    3*17 isn’t a common operation though and doesn’t show up in tables like that, so people probably aren’t generally familiar with it.
