%C Is a(n) = A101868(n-1) for n>1? - R. J. Mathar, Apr 01 2011

%C Yes: this follows from A188433(n) = 1 - A188009(n), for n > 2, using [-x] = -[x] - 1 for non-integer x. This implies the above, A188434(n) = A101868(n+1) = A101866(1,n+1), and also A188435(n) = A188010(n+1), for all n > 1. - _M. F. Hasler_, Dec 14 2017
