Here’s a way to get exactly your 30‐integer sequence in one leftmost derivation, by threading through the A58→A60 A59 and A3→A38→A39→A43/A47 branches, and just inserting the missing terminals in the two key “constant” productions:

Updated production rules:
rule_1459: A43 -> 25 16 15 18 A16 14 19 17 16
rule_1476: A47 -> 13 2 12 4 A14 11 5 3 2
