Because you say so? > The sum of all natural numbers is larger than ω. Wrong, it doesn't sum in the normal sense because it is not convergent. You could use the Zeta function for complex numbers and achieve -1/12 as a 'sum' in that sense. > Nevertheless ω-1 is the last natural number. Because you say so? Explain what minus one means in reference to omega.
