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

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

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

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

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

$100001$ $1color(white)(0000)1$

$700007$ $7color(white)(0000)7$

$8000010$ $8color(white)(0000)10$

$1000012$ $10color(white)(000)12$

$64000100$ $64color(white)(000)100$
