is there a list of valid triple indexes to initialize a nativestore?
I searched in the github repo rdf4j-storage but couldn't find an enumeration or something similar.

Triple stores use indexes based on subject, object, predicate and context. The index structure is given by the order of the first letter of each of these words, so, for example spoc, posc (these are the most common).
Any 4-letter permutation of these is accepted by RDF4J native store.
See for example https://github.com/eclipse/rdf4j-storage/blob/master/nativerdf/src/main/java/org/eclipse/rdf4j/sail/nativerdf/TripleStore.java, method parseIndexSpecList.

There is some documentation on this as well, although admittedly it's in an odd place: docs.rdf4j.org/server-workbench-console/#_native_store_indexes
