 A258640 Whole number sieve of square root of 2. 4

 OFFSET 1,2 LINKS Manfred Scheucher, Table of n, a(n) for n = 1..544 Manfred Scheucher, Sage Script EXAMPLE Find the first occurrence of 0 (the first whole number) in the digits of sqrt(2) (only 35 digits in this illustration): 14142135623730950488016887242096980..., and replace it with a space: 1414213562373 950488016887242096980...  Repeat the process with the next whole number, 1: 414213562373 950488016887242096980...  Then 2: 414 13562373 950488016887242096980...  Then 3: 414 1 562373 950488016887242096980...  Then 4,5,6,7, etc., until the first occurrence of every counting number is eliminated from the digits of sqrt(2).      1      3    4     8      9    ...  Then consolidate gaps between the remaining digits into a single comma: 1,3,4,8,9,80,9,69,0,7,7,8,2,0,5,3, ...  to produce the first terms in the whole number sieve of sqrt(2).
