 OFFSET 0,1 COMMENTS This number is the limiting expected overshoot over a boundary for the sum of independent and identically distributed normal variables with unit variance, as their positive mean approaches zero. It has applications in sequential analysis. LINKS G. C. Greubel, Table of n, a(n) for n = 0..10000 Joseph T.
