 Annual Appeal: Please make a donation to keep the OEIS running. In 2017 we replaced the server with a faster one, added 20000 new sequences, and reached 7000 citations (often saying "discovered thanks to the OEIS"). Other ways to donate

 OFFSET 0,4 LINKS EXAMPLE When powers of 4 are written in binary (see A098608), under each other as: 0000000000001 (1) 0000000000100 (4) 0000000010000 (16) 0000001000000 (64) 0000100000000 (256) 0010000000000 (1024) 1000000000000 (4096) and one collects their bits from the column=0 to NW-direction (from the least to the most significant end), one gets 1 (1), 00 (0), 000 (0), 0100 (4), 00000 (0), 000000 (0), 0010000 (16), etc. (see 0105033 for similar transformation done on nonnegative integers) CROSSREFS Cf.
