I think lcm (1 question) should be a synonym of least-common-multiple (52 questions), but I also heard that this was under large discussion currently.

I suggest barycentric-coordinates (1 question) as a synonym of analytic-geometry (1k+ questions).

Or maybe the tag just needs to be removed.

I suggest simple-functions (4 questions) as a synonym of elementary-functions (144 questions).

Do we really need java-applet (8 questions)?

Recently, automata (637 questions) was suggested as synomym of finite-automata (47 questions). I think it should be the other way around. We might also put cellular-automata (35 questions) in.

Please ping me to discuss. I have not done anything yet exepted for posting chat messages.
