Huitong posted this as a J-15S Batch 01 - the regular J-15 Batch 01 had only 10 aircraft - and indeed, the construction number 0115 indicates this to be already the 15th J-15S built.
Also, according the new "serial number" H1741049 this should be bort number 49.
Even more interesting, its H1741xxx number correlates with three other H-numbers, namely H1741030, H1741031 and H1741032 on three J-15s carrying the bort numbers 30, 31 and 32:
