Identifier for icons

I wonder how i can easily remember icons offline to retrieve them quickly. Or to be able to refer a colleague to a certain icon. Neither did I find an ID, nor a path leading to exactly one particular icon.

Hi! If you would like to get a path for one particular icon, please right-click on that icon and open it in a new tab.
Another way to do the same thing is to use the menu on the right side of each icon. Please choose “HTML” in the menu here:

%D0%A0%D0%B8%D1%81%D1%83%D0%BD%D0%BE%D0%BA1

You will see the link below:

%D0%A0%D0%B8%D1%81%D1%83%D0%BD%D0%BE%D0%BA2

For example, the link for that particular icon is: https://icons8.com/icon/3533/pi
I hope that it will help!
