A059904 Periodic part of continued fraction for sqrt(n), encoded by recursively interleaving the bits in the binary expansions of the repeating terms. 2
0, 4, 33, 0, 16, 516, 549755813899, 513, 0, 20, 549, 548, 604462909948052075708555, 549764202537, 545, 0, 64, 8208, 13479973333575319897333507543509815336818572211270286381289293482126 (list; graph; refs; listen; history; text; internal format)
OFFSET

1,2

COMMENTS

Could be made less gigantic by omitting final terms in continued fraction, which are always 2*c0.

LINKS

Table of n, a(n) for n=1..19.

FORMULA

a(n)=A059884(A059903(n))

EXAMPLE

sqrt(3)=1+[1,2] so a(3) is encoded as:

.....0 0 0 0 1 -> 1

....... 1 . 0 .-> 2

--------------

.....000100001 = 33.

CROSSREFS
