What is the meaning of 16*8 in the square dance "Yeyeye"?

That depends on which one it is! ! If we just say 16*8, my understanding is the action of 16 eight beats, counting from 1 to 16 eight beats.

1*8 is a bar, 16*8 is 16, a bar consists of 8 beats, and the number 1 2 3 4 5 6 7 8 is a bar.

1 2 3 4 5 6 7 8

2 2 3 4 5 6 7 8

3 2 3 4 5 6 7 8

4 2 3 4 5 6 7 8

until

16 2 3 4 5 6 7 8 (we don't count 16, an 8-back 1).
