OEIS Sequences

The r-th term of the n-th row of the following array contains the sum of r successively decreasing integers beginning from n. 0 < r <= n. Sequence contains the leading diagonal. A110427

Numbers that are the sum of 9 nonzero 8th powers. A3387

a(n) = (4·n+1)*(4·n+3). A1539

a(n) = 36n² - 1. A136017

a(1)=1; thereafter a(n) = smallest number m such that a(n-1)+m = (a(n-1) followed by the leading digit of m). A224752

a(2)=10; thereafter a(n) = smallest number m such that a(n-1)+m = (a(n-1) followed by the leading digit of m). A224761

Number of integer partitions of n whose negated first differences (assuming the last part is zero) are not unimodal. A332744

Numbers that are the sum of four positive cubes in four or more ways. A343971

a(n) = 9·n²-1. A136016

Start with a(1) = 1, and extend by the rule that the next term is the product of the two most recent non-terms of the sequence. A249406
