4276

**4276**

4276 is a two-digit number that holds significance in various contexts, particularly in mathematics, computing, and popular culture. In mathematics, it is often associated with the Fibonacci sequence, where the number appears as the 15th term (since Fibonacci numbers are typically indexed starting from 0 or 1). The sequence progresses as follows: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, and 987, making 4276 the 22nd term if counting from 1. However, in standard indexing (starting at 0), 4276 does not appear in the Fibonacci sequence.

In computing, 4276 is a notable port number used in the Transmission Control Protocol (TCP) for the **X.500 Directory Access Protocol (DAP)**, an older directory service standard. This protocol was part of the early networking protocols before the widespread adoption of LDAP (Lightweight Directory Access Protocol). It is also referenced in the context of **Sun Microsystems' Network File System (NFS)**, where certain services historically used this port number for inter-process communication.

Culturally, 4276 has appeared in references to the number 42, famously from Douglas Adams' *The Hitchhiker's Guide to the Galaxy*, where the answer to "the Great Question of Life, the Universe, and Everything" is 42. While 4276 is not directly tied to this joke, the number 42 itself is a playful placeholder, and the concept of arbitrary numbers in pop culture has led to similar playful associations.

Additionally, in some programming contexts, 4276 may be used as a constant or identifier, though its specific meaning would depend on the programming language or framework in question. Without further context, its precise significance remains limited to niche technical or mathematical references.
