Appears in sequences

• Factorial splitting: write n! = x*y*z with x<y<z and x maximal and z is minimal; sequence gives value of z.at n=18A061032
• a(n) = Sum_{k=0..floor(n/2)} k! * 2^k * (n - 2*k)!.at n=10A309618
• Factorial splitting: write n! = x*y*z with x <= y <= z and minimal z-x; sequence gives value of z.at n=21A355191
