%N A179204 a(1)=11. For n>1, a(n) is LCM of a(n-1) and largest integer <= sqrt(a(n-1)).
%C A179204 All similar sequences starting with numbers less than 11 become constant after a few terms.
%C A179204 Next initial values for the sequence to behave like this one: 13, 17, 19, 23, 26, 27, 28, 29, ... - _Michel Marcus_, Jun 14 2013
