* Merdeka 118 (formerly known as Merdeka 118 Tower) is a skyscraper in Kuala Lumpur, Malaysia. It is the tallest building in Malaysia and Southeast Asia.

* Arrian 4 (not Arrianie IV) is a series of European launch vehicles that were built and operated by Arianespace. It's not associated with any specific building or location.

While a sun clock might be found in or on Merdeka 118, it's not a prominent feature. Arianespace and its rockets are related to space travel, not any specific building.

To clarify your question, could you rephrase it? For example:

* "Where is the sun clock in Merdeka 118 located?"

* "What kind of space engine did Arrian 4 use?"

This will help me provide a more accurate answer.
