# Crossnumber 8: Martian

Here is one Crossnumber puzzle. In addition to the regular rules, both the clues and the grid use a number system of base greater than ten, with $\alpha$ being some digit greater than 9. No addresses are given for the clues, nor are they listed in order; all multidigit numbers in the grid, and multidigit numbers only, are clued.

$\bullet$ Not a multiple of 5.
$\bullet$ Not a multiple of 6.
$\bullet$ Not a multiple of 7.
$\bullet$ 397$\alpha$ + 3974.
$\bullet$ $\alpha$9 – 77.
$\bullet$ 68 $\times$ 8$\alpha$.
$\bullet$ $94^2$ + 888.
$\bullet$ 52 $\times$ 53.
$\bullet$ 16 $\times$ 19.
