Not an expert on group theory. But there is the trivial group of just one element. This could be labeled identity or something else. There is no group with count nill.

In my humble opinion the easiest group to understand is cyclic group. These cyclic group must have prime order. To be clear, the count of number of elements is a prime number.

In the end, don't know of a connection between quadratic surds, and mathematical groups.

Surely we can learn from the question of Original Poster.
