Examples
Find the first occurrence of 0 (the first whole number) in the digits of Phi (only 35 digits in this illustration): 16180339887498948482045868343656381..., and replace it with a space: 1618 339887498948482045868343656381... Repeat the process with the next whole number, 1: 618 339887498948482045868343656381... Then 2: 618 33988749894848 045868343656381... Then 3: 618 3988749894848 045868343656381... Then 4,5,6,7, etc., until the first occurrence of every counting number is eliminated from the digits of Phi. 1 3 9 48 04 8 ... Then consolidate gaps between the remaining digits into a single comma: 1,3,9,48,4,8,9,9,6,5,5,0,28,70,0, ... to produce the first terms in the whole number sieve of Phi.
