OEIS Sequences

Small-number statistic from the enumeration of domino tilings of a 3-pillow of order n. A112835

Expansion of (5 + 6·x + 3·x² - 2·x³) / (1 - 2·x - 2·x² - 2·x³ + x⁴) in powers of x. A71101

Define K(n) = Integral_t=-1..1 (t²ⁿ*(1-t²)²ⁿ/(1+it)³ⁿ⁺¹)dt, and write K(n) = a(n)*π - b(n)/c(n) where a(n), b(n), c(n) are positive integers; the sequence gives a(n). A123178

a(n) = 2·a(n-1) + 2·a(n-2) + 2·a(n-3) - a(n-4); a(0)=0, a(1)=1, a(2)=2, a(3)=5. A138573
