All known clues hidden in this image can be seen by applying a PCA distance projection of component 3, as seen above. This can be done using either forensically or sherloq.
The only thing I’ve added to the image is the straight lines connecting the “A” to “a” and “B” to “b”

1) 9619907

wiki

The Maersk 2013, a new Triple E-class container ship (165,000 metric tons deadweight), IMO:9619907, yard number 4250, ship name Mærsk Mc-Kinney Møller, was named for Mærsk Mc-Kinney Møller.

Motto: Per Aspera Ad Astra (“Through Hardships to the Stars”)

The fact that this ship is class “Triple E” points to E=3.
Rob has previously mentionedPer Aspera Ad Astra”.
”Æ” as in “Mærsk” also appeared in CB2_Guns_and_Namas.

The motto is used by many other organizations, and individuals, as well as in pop culture. Many of these uses have tenuous connections to the hunt (source).

2) A-a B-b cross

Drawing lines connecting the “A” to “a” and the “B” to “b” results in an X which marks the center of Namatama’s yolk.
