The initial rising point is 3.

After turning 90 to the right for the first time, the number of points facing up is 5.

After the second counterclockwise rotation of 90, the number of points facing upwards is still 5.

Then turn right 90, and the number of points up is 6.

After 90 counterclockwise rotation, the number of points facing upwards is still 6.

After rotating 90 to the right, the number of points facing upward becomes 3, but the number of points facing forward is 2 at this time.

So it turns 90 counterclockwise and returns to its original appearance, that is, the number of points in front of it is 1 and the number of points up is 3.

So according to the above rules, 6 operations are 1, so if the operation is 20 12.

It is 20 12 ÷ 6 = 335...2.

It was cycled 335 times and operated twice.

According to the law in Figure 2, after two operations, the number of points facing upwards is 5.

So the answer is: 5.
