OEIS Sequences

Centered square numbers: a(n) = 2·n*(n+1)+1. Sums of two consecutive squares. Also, consider all Pythagorean triples (X, Y, Z=Y+1) ordered by increasing Z; then sequence gives Z values. A1844

Partial sums of sequence of odd primes (A065091); a(n) = sum of the first n odd primes. A71148

Number of partitions of n in which the least part is even. A26805

a(n) = 8·n² - 4·n + 1. A80856

a(1)=1, a(n)=a(n-1)+n if n odd, a(n)=a(n-1)+ n² if n is even. A140113

Numbers m that are the hypotenuse of exactly 13 distinct integer-sided right triangles, i.e., m² can be written as a sum of two squares in 13 ways. A97102

Number of connected cyclic conjugacy classes of subgroups of the symmetric group. A218970

Least hypotenuse of primitive Pythagorean triangles with odd leg 2n+1. A96891
