Note this requires ~240 gold @turn 26.
I claim no further optimization is possible without lucky ancient ruins or El Dorado or super-early worker steal from high-level AI/player or AI luxury for gold trading coupled with unit purchasing. Great Library/tradition/aristocracy builds to do a "Mini Sword rush" are about the same speed, but for 2 swords and with a much smaller base.
