D(n)=n(D(n-1) arrows)n(D(n-1)factorial signs)
and D(1) = 1
so D(2) = 2^2!
and D(3) = 3^^^^^^^^^^^^^^^^^^^^^^^^3!!!!!!!!!!!!!!!!!!!!!!!! (D(2) or 24 arrows and factorials)
and D(4) is 4(D(3) arrows)4(D(3) factorial signs)
4^^^^^^^^^^^...…….^^^^^^^^^^^^^4!!!!!!!!!!!!…..!!!!!!!!!!!
^ D(3) arrows ^D(3) factorials
my number is D(50)
this is like 1/transfinity or something size of the omniverse
