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 0,5 COMMENTS The value of the fine-structure constant is given approximately by the square root of this constant. Also an approximate value of the classical electron radius, expressed in atomic units. Briddell noted that the integer 18779 can be derived from the Sierpinski triangle (see the Briddell's paper, page 60).
