请解答---**Description:** 完全四边形各边共交成四个三角形，他们的内心、旁心共16点。在每个三角形中分别以内心、旁心两的连线为直径作圆，如此一共可得24个圆。这24个圆，除三三交于各三角形的内心、旁心外，又三三交于其他16点。这16点连同各三角形的内心、旁心计32点，分布在8个圆上。每圆上有8点。这8圆组成两组互相正交的共轴圆，每组含四圆，它们的等幂轴同过完全四边形的米克尔点。 **Geometric Diagram Description:** * **Type:** Complex geometric construction diagram. * **Main Elements:** * **Points:** The diagram features a high density of labeled points. These include: A, B, C, D, E, F, I, K, L, M, N, O, P, Q, R, S, I', P', Q', R', S', P_1, P_2, P_3, P_4, P_h, P_k, Q_1, Q_4, P_A, P_B, P_E, Q_D, R_A, R_B, R_C, R_D, S_A, S_C, S_D, S_E, S_1. Additionally, there are 8 points explicitly marked as centers of circles: O_1, O_2, O_3, O_4, O_5, O_6, O_7, O_8. (Note: O also appears as an unlabeled point near the center of the diagram). * **Lines:** Numerous straight lines intersect each other, forming a complex network of triangles and quadrilaterals. Many lines connect the labeled points, and some extend outwards. * **Circles:** Eight distinct circles are prominently drawn and labeled with their respective centers (O_1 to O_8). These circles intersect with each other and with many of the straight lines. The text mentions 24 circles in total, but only 8 are explicitly drawn and labeled with centers in the diagram. * **Shapes:** The diagram visually represents the geometric configuration described in the text, focusing on the intersections and relationships within a "complete quadrilateral" (implied by the outer structure formed by lines connecting points like P_B, S_C, Q_D, P_A, S_D, etc.) and its associated triangles. Numerous triangles are formed by the intersecting lines. * **Labels and Annotations:** All points are labeled with letters, often with subscripts or primes (e.g., P_B, O_1, P', S_C). The labels are placed near their corresponding points. * **Relative Position:** The diagram shows a central region with a very dense network of intersecting lines and points, surrounded by the eight large circles. Several labeled points (e.g., P_B, S_C, Q_D, P_A, S_D) are positioned towards the periphery, suggesting the vertices or key points of the larger complete quadrilateral structure. The circles O_1 to O_8 are positioned such that they encompass or pass through many of the interior and exterior points and intersections.
