0.010841015122311136151129081140641509112215809093909091; The Trott constant. (from Michael Trott, Champaign, IL, that dreamed about it on Feb 21, 1999). That constant is invariant, if we expand the number digit by digit as if it would be a continued fraction then the number is the same. That is : [0,1,0,8,4,1,0,1,5,...], of course the '0' have to be collapsed, as seen as a continued fraction has a decimal expansion which is 0.0108410151223111...
