NAME

Numbers a(n) k in pairs of numbers (b(n), a(n)j,k), with b(n) j <> (a(n) k +- 1), , such that the sum of their cubes is equal to a centered cube number.

COMMENTS

Numbers a(n) k such that b(n)j^3 + a(n)k^3 = c(n)m^3 + (c(n) m + 1)^3 = d(n), N, with b(n) j <> (a(n) k +- 1), b(n) j > c(n), b(n) m and j > |a(n)k|, and where b(n) j = A352135(n), ck = a(n) (this sequence), m = A352134(n) and d(n) N = A352133(n).

In case there are two or more pairs of numbers (b(n), a(n)j, k) such that the sum of their cubes equals the same centered cube number, the value of a(n) corresponding to the smallest occurrence of b(n) = A352135(n) j is shown in the sequence. For other occurrences, see A352224(n) and A352225(n).

Terms in Data are ordered according to increasing order of A352133(n) or A352134(n).
