Leonid Kimelfeld (Jan 22 2019 at 07:58):

Dear all, could you help me. Where is formalization of Lagrange theorem (group theory) in mathlib?

Mario Carneiro (Jan 22 2019 at 08:02):

card_subgroup_dvd_card, I guess? https://github.com/leanprover/mathlib/blob/master/src/group_theory/order_of_element.lean#L56-L58

Mario Carneiro (Jan 22 2019 at 08:02):

there are a few ways you could state the theorem
