For the literal-minded and those unfamiliar with terms like "base thirteen," 42 in a system where "10" equals decimal "13" is the same as four 13s plus 2, or decimal 54. So "six by nine" or decimal 54 is, in base 13, 42. For the mystically inclined, 42 in base 13 is the same as 110110 in binary (base 2).
