From threeA Wiki
7174 Pty. Ltd. (7174 for short) is Ashley Wood and T.P. Louise's parent company for protecting their intellectual properties. Most of Ash's creations are copyrighted under this company while T.P. is known for writting for 7174 (as seen in the credits of the books that she and Ash have worked on).
Not much is known about this company, but there are other "helpers" employed with 7174 behind the scenes [1].
