You should look in the 3rd part, chapter 22, under "The Basic Types".
Table 22.2, page 306 (in my PDF edition).

It says :

|     Table 22.2. Substitutions in double-quoted strings
| --------------------------------------------------------------
| \a Bell / alert (0x07)                \nnn     Octal nnn
| \b Backspace (0x08)                   \xnn     Hex nn
| \e Escape (0x1b)                      \cx      Control-x
| \f Formfeed (0x0c)                    \C-x     Control-x
| \n Newline (0x0a)                     \M-x     Meta-x
| \r Return (0x0d)                      \M-\C-x  Meta-control-x
| \s Space (0x20)                       \x       x
| \t Tab (0x09)                         #{code}  Value of code
| \v Vertical tab (0x0b)
| --------------------------------------------------------------

So, your example uses the octal representation.
