Question

For any prime factor p of the order, some of these objects named after Ludwig Sylow exist. For 10 points each:
[10m] Name these algebraic objects, whose order divides that of their superset according to Lagrange’s Theorem. If their left and right cosets are equal, they are considered “normal.”
ANSWER: subgroups [accept normal subgroups; accept Sylow p-subgroups; do not accept or prompt on groups]
[10h] Normal subgroups are invariant under this operation for elements of the group. This operation divides group elements into “classes” with similar algebraic properties.
ANSWER: conjugation [accept conjugacy classes; accept conjugate elements]
[10e] Normal subgroups are notably closed under this binary set-theoretic operation, which is defined for two sets as the set of elements that lie in both sets at once.
ANSWER: intersection
