Appears in sequences

• Define a sequence u(n) by u(1)=1; thereafter u(n) = f(n)/f(n-1) where f(n) = (-1)^(n+1)*A105750(n); sequence gives numerator(u(n)).at n=12A220448
• a(n) is the numerator of the real part of Product_{k=1..n} (1/k + i) where i is the imaginary unit.at n=12A370547
• a(n) is the numerator of the imaginary part of Product_{k=1..n} (1 + i/k) where i is the imaginary unit.at n=12A370553
