It's the blue app icon with a white lowercase "f" usually located on your home screen. You can browse for a group page on your wall or by typing the name of the group in the search bar at the top. Tap the white info button with the lowercase "i" in the top-right of the screen. This opens the Group Info page. On iPad, tap ⋯ in the top-right and then tap View Group Info instead. It's the second option on the Group Info page.  It's next to an icon with a curved arrow.  This displays a pop-up menu from the bottom of the screen. If this option is not listed, you may need to be a member of the group before you can copy the URL. It's near the bottom of the pop-up menu just above the "Cancel" option. This copies the link to your iPhone or iPad's clipboard, allowing you to paste it elsewhere. You can paste the link in any app that allows you to write or edit text.  This can be another Facebook post, instant message, text message, email, or text document.  To paste the link, tap and hold the text cursor until you see the black bar above the cursor appear and then tap Paste.
