21. Autonomous systems are closely related to dynamical systems.22. A " transit " autonomous system is an AS that provides connections through itself to other networks. 23. The accepted textual representation of autonomous system numbers is defined in RFC 5396 as " asplain ". 24. For a second-order linear autonomous system , a characteristic equation has one positive and one negative real eigenvalue. 25. Routing domains are also called autonomous systems . 26. Boeing used its aircraft, spacecraft, and autonomous systems experience to work with its team including Blue Origin. 27. It can be a consequence of dualist theory that international and national law are independent autonomous systems . 28. Since the operational area within the Colony was so vast, the CGR was divided into three semi-autonomous systems . 29. BBN was the first networking organization to receive an Autonomous System Number ( AS1 ) for network identification. 30. A group of networks that operate under a single external routing policy is known as an autonomous system .
