OEIS Sequences

Square pyramidal numbers: a(n) = 0² + 1² + 2² + ... + n² = n*(n+1)*(2·n+1)/6. A330

Structured rhombic dodecahedral numbers (vertex structure 9). A100157

Numbers n such that the decimal expansions of both n and n² have 2 as smallest digit and 7 as largest digit. A257123

Numbers k such that k and k+1 are the product of exactly four distinct primes. A318896

a(0)=0; then a(4·k+1)=a(4·k)+(4·k+1)², a(4·k+2)=a(4·k+1)+(4·k+3)², a(4·k+3)=a(4·k+2)+(4·k+2)², a(4·k+4)=a(4·k+3)+(4·k+4)². A115391

The number of binary pattern classes in the (2,n)-rectangular grid with 3 '1's and (2n-3) '0's: two patterns are in same class if one of them can be obtained by a reflection or 180-degree rotation of the other. A225972

a(n) = s(1)*s(n) + s(2)*s(n-1) + ... + s(k)*s(n+1-k), where k = floor((n+1)/2), s = (odd natural numbers). A24598

Even square pyramidal numbers. A15222

Consider the line segment in Rⁿ from the origin to the point P=(1,2,3,...,n); let d = squared distance to this line from the closest point of Zⁿ (excluding the endpoints). Sequence gives d times P.P. A59774
