An odd inequality sign

I saw this rather odd symbol of the the greater sign on top of the less sign in my lecture notes. I am wondering if there is a name for this symbol and if signifies 'equal to' as well?

?

I would interpret that as "is not equal to".

Is it any of these?

$$\lessgtr, \quad \gtrless,\quad \lesseqgtr,\quad \gtreqless,\quad \lesseqqgtr,\quad \gtreqqless$$

Is it any of these?

$$\lessgtr, \quad \gtrless,\quad \lesseqgtr,\quad \gtreqless,\quad \lesseqqgtr,\quad \gtreqqless$$
I'd say it'd probably be the second one.
