Original definition: Let u(0)=1, u(n) = Pi * floor(u(n-1)), then a(n) = u(n)/Pi.

This is equivalent to a(n)=floor(u(n-1))=floor(Pi*a(n-1)), a(1)=1. So it should be A134915(n-1), but the given values do not correspond to that definition, as observed by H. P. Dale and R. Israel. - M. F. Hasler, Oct 15 2012
