Choi Seok-jeong (Korean: 최석정; Hanja: 崔錫鼎; 1646–1715) was a Korean politician and mathematician in the Joseon period of Korea.
He published the Gusuryak (Korean: 구수략; Hanja: 九數略) in 1700,[1] the first known literature on Latin squares,[2] predating Leonhard Euler by at least 67 years.[3][4] He also invented the hexagonal tortoise problem.[5] Choi was a member of the Jeonju Choe clan.
