G. C. Greubel, Table of n, a(n) for n = 0..5000
FORMULA
It seems that a(n) = 3*n + o(n); conjecture : a(n) = 3*n + O(1).
MATHEMATICA
With[{r = Sqrt[3]}, Select[Range[0, 200], Floor[#*r*Floor[#/r]] == Floor[(#/r)*Floor[#*r]] &]] (* G. C. Greubel, Feb 06 2019 *)
PROG
(PARI) r=sqrt(3); for(n=0, 200, if(floor(n*r*floor(n/r))==floor(n/r*floor(n*r)), print1(n, ", ")))
