Whilst it seems attractive to utilize "Text" speech in a post I can assure you that our community does not face the same character limitation as Twitter or a SMS.
I can therefore only encourage yourself to utilize the full product names as non native English speakers or our community search engine may struggle to understand what you are asking.
I am unsure myself what a Real Presence Mobile would have to do with the serial Number of a GroupSeries.
Could you therefore kindly restructure your question ?
