EXAMPLE
|
Find the first occurrence of prime 2 in the digits of Phi (only 40 digits in this illustration):
161803398874989484820458683436563811772..., and replace it with a space:
1618033988749894848 0458683436563811772... Repeat the process with 3:
16180 3988749894848 0458683436563811772... Then 5:
16180 3988749894848 04 8683436563811772... Then 7:
16180 3988 49894848 04 8683436563811772... Then 11, 13, 17, etc., until the first occurrence of every prime is eliminated from the digits of Phi.
1 80 3988 49 4848 04 86 6 8 772... Then consolidate gaps between the remaining digits into a single comma:
1,80,3988,49,4848,4,86,6,8,7720309,... to produce the first terms in the prime sieve of Phi.
