The expression on the right-hand side is abbreviated to 111378 and is the representation of this number to base 8 (or octal). In general, if g is an integer greater than 1, any positive integer a can be written uniquely as

where each ci is a non-negative integer less than g. This is the representation of a to base g and is abbreviated to inline.
