Context triple: [OEIS A064988, isMaintainedBy, The OEIS Foundation]

• A. OEIS A064988
  OEIS A064988 is the entry in the On-Line Encyclopedia of Integer Sequences that records the decimal expansion of Gauss’s constant, a notable mathematical constant arising in elliptic integrals and number theory.
• B. Ulam sequence
  The Ulam sequence is an integer sequence starting with 1 and 2 in which each subsequent term is the smallest integer that can be written uniquely as the sum of two distinct earlier terms.
• C. Ramanujan’s sum
  Ramanujan’s sum is a number-theoretic function introduced by Srinivasa Ramanujan, expressing certain periodic arithmetic functions as finite trigonometric sums over primitive roots of unity.
• D. Zeckendorf
  Zeckendorf is a surname most notably associated with American real estate developer William Zeckendorf and his influential role in mid-20th-century urban development.
• E. Sylvester sequence
  The Sylvester sequence is an integer sequence defined recursively where each term is one more than the product of all previous terms, yielding rapidly growing, pairwise coprime numbers closely related to Egyptian fraction representations.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
