• a(n) = binomial(n+6,6)*(2n+7)/7.at n=13A050486
• Jacobi form of weight 12 and index 1 for Niemeier lattice of type E_6^4 or A_11 D_7 E_6.at n=8A055757
• Amicable triples: numbers such that sigma(x) = sigma(y) = sigma(z) = x+y+z, x<y<z. We order these triples according to the common value of sigma. Sequence gives y numbers.at n=26A125491

• Numerator coefficients for generators of lattice path enumeration square array A111910.at n=38A140136
• Convolution square of A058187, the tetrahedral series with repeats.at n=26A178440
• a(1)=0; for n>1, a(n) = 4*n^3 - 3*n^2 - 3*n + 4.at n=31A296363
• a(n) is the index of the first occurrence of n in A331284.at n=43A331285
