OEIS Sequences

a(n) = ∑_k=0..n (-1)^k * binomial(n, k) * q(k), where q(k) is A000009 (partitions into distinct parts). A293467

Triangle T that satisfies the matrix products: C*[T^-1]*C = T and T*[C^-1]*T = C, where C is Pascal's triangle. A118801

a(n) = (-1)ⁿ * (1 - 2ⁿ). A225883

a(n) is the largest power of n such that all numbers n^k <= a(n), k=1,..,A336778(n)-1 can be exactly represented as double precision 64-bit floating point numbers according to the IEEE 754 standard. If a(n) is a power of 2, it is replaced by the corresponding negated exponent of 2. A336779

a(n) = 1 - n⁵. A24003

Triangle T(n,k) = (-1)^k * A119258(n,k) read by rows, 0 <= k <= n. A145661
