OEIS Sequences

a(n) = 4ⁿ - 3ⁿ - binomial(n,2)*3^n-2. A380024

Composite numbers whose prime factors contain no digits other than 7 and 8. A36323

The number of partitions of n which represent Chomp positions with Sprague-Grundy value 8. A284781

Triangle T(n,r) read by rows: order of the semigroup of orientation-preserving partial transformations of n elements with breath r. A289710

a(n) = ∑_{k=0..floor(n/2)} A027144(n-k, k). A27154

Number of numbers k which give 1 after applying exactly n iterations of the 3k+1 algorithm (if a number is even, divide it by 2; if it is odd, multiply by 3 and add 1). This total includes numbers k which also give 1 for a smaller number of iterations (i.e., for this sequence we do not assume the algorithm halts when 1 is reached). A82538
