Internal parallel 1 consists of Aa3-6--15 / Ab2-34--40, the central part of which is:

Aa3-8	Aa3-9	Aa3-10	Aa3-11

Ab2-35	Ab2-36	Ab2-37	Ab2-38

Internal parallel 2 is much longer, and the part we are interested in could be described as:

Ab3-7	Ab3-8	Ab3-9	Ab3-10	Ab3-11	Ab3-12

Ab5-16	Ab5-17	Ab5-18	Ab5-19	Ab5-20

Both parallels will be discussed briefly: internal parallel 1, internal parallel 2.
