A005153

A005153 is an identifier used in the On-Line Encyclopedia of Integer Sequences (OEIS) for a particular integer sequence. The OEIS entry associated with this identifier provides a precise definition of a(n), along with initial terms, as well as various mathematical properties and context. The sequence may arise from combinatorial counting, number theory, or algebra, and is accompanied by notes on interpretation and possible generalizations. Typical OEIS entries include one or more of the following: a formal recurrence relation, a closed-form expression when available, a generating function, and asymptotic behavior. They also provide references to mathematical literature and cross-references to related sequences. A005153's page may include example computations, connections to other combinatorial objects, and descriptions of special cases or modular properties. The sequence is cataloged for use by researchers and students who study integer sequences, discrete mathematics, or computational number theory. Updates to the OEIS entry may occur as new interpretations or proofs are published. For researchers, the identifier A005153 serves as a persistent link to all known information about the sequence, including programmatic data for computation and links to related sequences.
