LSG TrID list-version index size-of-list group-id group-name 0

Where list-version is the current List Version.

Where index is a number that can not go out of size-of-list. If you have not added any groups, this value is always 1.

Where size-of-list is the upper bounds for index. If you have not added any groups, this value is always 1.

Where group-id is the relevant group's identification number, allowed values are 0 to 29. If you have not added any groups, this value is always 0.

Where group-name is the relevant group's display name, URL encoded if needed, up to 61 bytes. If you have not added any groups, this value is always ~.

Where 0 is always 0.

# Client-initiated

# No groups created

NOTE: Specifiying this as the LSG in SYN will cause the client to attempt to re-initialize the default groups. Please review the SYN page for what the client attempts to do here.
