Yup, 1,2,3,4 or 0,1,2,3. Different mean, same sigma. Or 1,1,1,1, if allowed.

Standard deviation has to do with how spread out they are. It's more than that, but spread is the basic idea.
"that the standard deviation of the set is as low as possible."
Pick them so they are tightly bunched. Heck, make them all the same, then the spread is 0.
"so that the standard deviation of the set is as high as possible. "
Spread them out as much as possible.
