 OFFSET 1,1 COMMENTS One expects Pi^2 to be equidistributed, base 2, with an equal asymptotic density of 0 and 1 in this sequence; equal density of 00, 01, 10, 11. The first 100 decimal places here have, as binary, a run of 7 0's and a run of 9 1's. LINKS Table of n, a(n) for n=1..105. FORMULA Pi^2 (base 2). EXAMPLE 1001.1101111 (base 2) ~ 9.8696 (base 10) ~ Pi^2. 100 decimal places precision here. See also: A000796 Decimal expansion of Pi. See also: A004601 Expansion of Pi in base 2.
