Thickafourtwelvearialearth  is equal to \(10^{2,134,524,089,369,833,840,414}-1\). This is the first number coined by Brazilian amateur googologist Daniel Corrêa. It is  2,134,524,089,369,833,840,415  digits long and its decimal expression is  9999999921345240893698338404159

Using Jonathan Bower's -illions series , Thickafourtwelvearialearth can be named:

Creation process
The creation process of Thickafourtwelvearialearth has a "physical meaning":

 ​ 
 * 1) Write a complete line of 9's in a Bond A4 Copy Paper 75gsm using Regular Arial 12 as font;
 * 2) Measure the width of number nine (1.9 mm) and the space between two nines in sequence (0.42 mm);
 * 3) Measure the thickness of the paper (0.103 mm);
 * 4) Imagine the Earth as a perfect smooth sphere with radius equal to 6,371,008,771.415 mm, value of the mean radius defined by the IUGG using the radius of the WGS-84 ellipsoid;
 * 5) Imagine you cover the whole surface of the Earth with a flat spherical spiral in vertical position, this spherical spiral made of a very long paper strip with 9's written on it as described in (1.);
 * 6) When doing some calculations, you will find that the total length (L) of such spherical spiral described above is 4,952,095,887,338,014,509,763.439 mm;
 * 7) Knowing the length of the strip, you can find the number of digits (n) written on it;
 * 8) The formula for (n) is n = (L+0.42)/2.32, and doing the calculations you can find that n is 2,134,524,089,369,833,840,415 .456.
