Indeed.

[math]G=(\{2,5\},+,5) \\ G \cong \mathbb{Z}_2 \Rightarrow 2+2=5[/math]

You never know!

Let [math]f(n)[/math] denote the size of biggest possible subset [math]S \subseteq \{1, 2 \dots n \}[/math], such that for any [math]i, j \in S[/math], their difference [math]|i - j|[/math] is not a square.
What are the asymptotics of [math]f[/math]? no one knows
why is modern math so cucked, we are unable to solve such simple problems
