OEIS Sequences

Consider the Diophantine equation x³ + y³ = z³ + 1 (1 < x < y < z) or 'Fermat near misses'. Sequence gives values of z in monotonic increasing order. A50791

a(n) = concatenation of n² and n. A55436

a(n) = 100·n² + n. A55438

Expansion of ∏_k>=1 B(x^k), where B(x) is the g.f. of A003106. A327691

Subsequence of 'Fermat near misses' which is generated by a simple formula based on the cubic binomial expansion along with formulas for the corresponding terms in the expression, x³ + y³ = z³ + 1. A141326
