A106537 The decimal digits of sqrt(2) = A002193 split into groups as long as given by the string of digits themselves. 1

COMMENTS

The decimal expansion is divided into chunks of lengths of 1, 4, 1, 4, 2 etc. Where a chunk would start with a leading zero, sizes are increased to have a length determined by 2 or more consecutive digits, as for a(6) which does not contain 1 but 13 digits.

The next chunk of the sequence will have 880 digits.

EXAMPLE

1 4142 1 3562 37 3095048801688 72420 969807 85 696 7187537... 1 4 1 4 2 13 5 6 2 3 7

Chunk "3095048801688" could not be divided into chunks of size 1, 3, 5, etc. because of the 0 (zero) in second position.
