This problem wants us to find the first n integer roots of the 666 function. It took me a while to understand this problem. The first integer root is at sind(666)-cosd(6^3).

The notation 'nnn' is shorthand for "concatenate three copies of n". As I understand the problem, the roots of the function (i.e., the values of n at which the function is zero) are 6, 15, 18, 27, etc. However, we are to output 'nnn': 666, 151515, 181818, 272727, etc.

Although technically correct, this is sort of vexatious.

I've now submitted a less vexatious answer :)

"Technically correct" is the best kind of correct. :-)
