This site is supported by donations to The OEIS Foundation.

 Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing. Other ways to donate

 OFFSET 0,2 COMMENTS The first player can move the ball 2a_n spaces before the second player can move the ball 2(a_{n-1}+1) spaces A self-describing sequence. Pick any number n; this n says: "There are n terms in the sequence which are <= 2n". This sequence is the slowest increasing one with this property. - Eric Angelini, Jun 15 2007 REFERENCES Berlekamp, Conway and Guy, "Winning Ways", Volume 2.
