$0,1,2,3,4,5,6,7$

The octal numbering system uses 8 digits (this is compared to the decimal system using 10 digits). The octal system uses:

$0,1,2,3,4,5,6,7$

To see how this works, let's compare a few decimal numbers to octal numbers:

$"D" color(white)(000) "O"$

$1color(white)(0000)1$

$7color(white)(0000)7$

$8color(white)(0000)10$

$10color(white)(000)12$

$64color(white)(000)100$
