Set theory as well..........b/c the 1st 18 .....is at 4.............4 - 7.............4 + 7 = 11.....some tables have 4 - 6...........as the full 18........as in continuous....................4 + 6 = 10...........4 + 7 = 11..........11/10.....the 5th term of Euler's product with a s of 1.........

2(3/2)(5/4)(7/6)(11/10).........the 1st 5 terms of Euler's product with a s of 1................5/4 is like a vertical..........45...going from bottom up.........7/6 and 11/10 are the 4th and 5th respectively......just like 459045.............11 - 16 th numbers in e...............and a fractal e....b/c 11 + 16 = 27...........horizontals and verticals.........7 down...a vertical.....m = undef or infinity of a vertical line...........m = 0 on a horizontal line...................a rectangle missing a piece.....like a Riemann sphere.....a ball........3d circle...a sphere...with a hole at the top.....................some have 6 down..some have 7 down.....in the "main" part of the periodic table..like 7/6 for Euler's product.....i bet b/c the actual answer varies..............the number of elements in nature is not fixed......it depends...it varies......and some are man made or alien made.....nature makes some...........the idiotic mad scientists make some.......most things are relative.....Dr. Einstein...
