0o4756

0o4756 is an octal literal prefix 0o used in programming languages such as Python to denote the base-8 number formed by the digits 4, 7, 5, and 6. The value in decimal is 2542 (4×8^3 + 7×8^2 + 5×8 + 6).

In Unix-like systems, this four-digit octal code is also used to describe file permission bits: the leading digit is the special mode, followed by owner, group, and other permissions. For 4756: the leading 4 indicates the setuid bit is set; owner permissions are 7 (read, write, execute); group permissions are 5 (read, execute); and other permissions are 6 (read, write). Therefore the symbolic representation for a regular file would be -rwsr-xrw-. If applied to a directory, setuid is unusual; more commonly involved would be setgid or sticky bits.

In programming contexts, 0o4756 can be used as a numeric value in bitwise operations; its decimal equivalent is 2542.

Security considerations: setuid bits can elevate privileges and pose risks; use only on trusted executables and with careful access control.
