OEIS Sequences

For a positive number k, let L(k) denote the list consisting of k followed by the prime factors of k, with repetition, in nondecreasing order; sequence gives composite k such that the digits of L(k) are in nonincreasing order. A372034

Number of step shifted (decimated) sequences using exactly two different symbols. A56376

Expansion of ∏_k>=1 ((1 + x^{2·k - 1})/(1 - x^{2·k - 1}))^k². A294755

Semiprimes (A001358) made of nontrivial runs of identical digits. A116063

a(1) = 0 and a(n+1) > a(n) is the smallest integer such that a(n+1)²-a(n)² is triangular. A358416

Slowest increasing and self-describing sequence: first 2 digits are prime digits, followed by 3 composite digits, then 4 prime digits, then 6 composite digits, then 8 prime, then 2 composite, then 2 prime, etc. A105808
