• Number of partitions satisfying 0 < cn(2,5) + cn(3,5).at n=42A039897
• Total number of parts greater than 1 in all partitions of n minus the number of partitions of n into parts each less than n.at n=33A198381
• Numbers n such that sum of cubes of digits of n equals the sum of prime divisors of n.at n=21A217531
• Solution of the complementary equation a(n) = 2*a(n-1) - a(n-3) + b(n-2), where a(0) = 2, a(1) = 4, a(2) = 6, b(0) = 1, b(1) = 3, b(2) = 5, and (a(n)) and (b(n)) are increasing complementary sequences.at n=18A295618
• Expansion of 1/sqrt((1 - x^4)^2 - 4*x).at n=9A376792
• a(n) = the smallest positive integer that produces a product that contains the digit 2 when multiplied by 2 at most n times, and where a further multiplication by 2 produces a number that does not contain the digit 2. Set a(n) = -1 if no such number exists.at n=19A381183
