OEIS Sequences

a(n) = n*(n + 1)*(n² - 3·n + 5)/6. A6484

Numbers that are the sum of three positive cubes in four or more ways. A343968

Numbers that are the sum of three positive cubes in exactly 4 ways. A343969

Lexicographically earliest unbounded aliquot-like sequence based on the Dedekind ψ function: a(1) = 318, a(n) = t(a(n-1)) where t(k) = A001615(k) - k. A323328

Aliquot sequence starting at 966. A14363

Records of the maxima of the unitary aliquot sequences of the numbers in A290145. A290146

Smallest number which can be decomposed into exactly n sums of three distinct positive cubes, but cannot be decomposed into more than one such sum containing the same cube. A347362

a(1)=1; for n >= 1, a(n+1) is minimal such that there are a(n) primes strictly between a(n) and a(n+1). A82278
