• Number of partitions into non-integral powers.at n=25A000158
• Multiplicity of highest weight (or singular) vectors associated with character chi_15 of Monster module.at n=41A034403
• a(2n) = concatenation of 4n+1 and 4n+2, a(2n+1) = concatenation of the two most nearly equal numbers whose product is a(2n).at n=39A068517
• a(1) = 3; a(n) = smallest number such that the forward as well as the reverse n-th partial concatenation is a prime for n>1. (Reverse concatenation is taken term-wise and not digit-wise).at n=17A083993
• Sum of the prime(n) primes following prime(n).at n=21A099274
• The number of digits in the next largest juggler number.at n=12A143743
• The first integer that produces a sequence of n terms without repetition. Any term of the sequence, after the first one, is the sum of PD and SD of the previous term of the sequence. PD is the product of the nonzero digits; SD is the sum of the digits.at n=8A235031
• Number of length 3+2 0..n arrays with some pair in every consecutive three terms totalling exactly n.at n=15A245872
• Expansion of Sum_{n>=0} x^n * Sum_{k=0..n} C(n,k)^2 * x^(2*k).at n=16A246840
• Table read by rows: T(n, k) = T(n, k-1) + m * T(n-1, n-k) for k > 1, T(n, 1) = T(n-1, n-1), and T(n, 0) = 0^n, for m = 2.at n=42A385895
