• a(n) = (n+1)(n+2)^3*(n+3)^3*(n+4)(2n+5)/4320.at n=6A107942
• Numbers with prime factorization pqr^3s^5.at n=10A190475
• Numbers k such that sigma(k) = 3*sigma(k+1).at n=5A217791
• Consider numbers n = concat(w,x,y,z) such that w*x*y*z | n. Leading zeros in x, y and z allowed. Sequence lists numbers that admit at least two such concatenations.at n=11A257172
• a(n) = 12*binomial(n, 5).at n=18A300847
• Coefficients of a family of orthogonal polynomials. Triangle read by rows, T(n, k) for 0 <= k <= n.at n=41A322944
• a(n) is the least k such that the denominator(sigma(sigma(k))/k) equals n.at n=41A331033
• Numbers m such that the equation m = k*sigma(k) has more than one solution.at n=8A337873
