interesting note about the term "octal" which in shapes means 8 sides.
in math it only includes the numbers 0 through 7,, and excludes 8, yet its called base 8 counting system since 0 is a number.

example.. octal digital address of 111 is equal to decimal 7

counting systems comes to mind....
base 2=binary
base 8=octal
base10=decimal
base16=hexedecimal
Base 60=Sexagesimal notation (for clocks)
