There are many tap dances, including 8 steps, 10, 12, 14, 16, 24 ... 100. You can find a lot by typing "XX steps of square dance" in sogou.

I recommend Dance Melody 2007 Square Dance to you. They uploaded a lot of footstep dances, such as "Step: Co Co Jambo" (24 steps), Step 24, Sudden Self (14 steps), and so on.
