Abstract
Let be the group of finitely supported permutations of a countably infinite set. Let be the group algebra of over a field of characteristic . According to a theorem of Formanek and Lawrence, satisfies the ascending chain condition for two-sided ideals. We study the reverse mathematics of this theorem, proving its equivalence over RCA (or even over RCA) to the statement that is well ordered. Our equivalence proof proceeds via the statement that the Young diagrams form a well partial ordering.
