OEIS Sequences

Expansion of ∏_k>=1 (1 + (k-1)*x^k). A267007

Fibonacci-like numbers with nonincreasing positive digits. Let a** denote the number that is obtained from a if its digits are written in nonincreasing order. Let a<+>b = (a + b)**. a(0)=0, a(1)=1, for n>=2, a(n) = a(n-1) <+> a(n-2). A237575

a(1) = 1; a(n+1) is the smallest integer > 0 that cannot be obtained from the integers {a(1), ..., a(n)} using each number exactly once and the operators +, -, *, /. A357891

a(n) is the largest number such that all of a(n)'s length-n substrings are distinct and divisible by 21. A93221
