SUMMARY

A group of order 12p is solvable for any prime p greater than 11. This conclusion is based on the fact that every group of order 12 is either isomorphic to A4 or contains an element of order 6. The subgroup H of order p is normal in G, allowing the solvability of G to be determined by the solvability of H and the quotient group G/H. Since H has prime order and G/H has order 12, both are solvable, confirming that G is solvable.

PREREQUISITES
  • Understanding of group theory concepts, specifically group order and solvability.
  • Familiarity with the properties of the alternating group A4.
  • Knowledge of normal subgroups and quotient groups.
  • Basic comprehension of prime numbers and their significance in group orders.
NEXT STEPS
  • Study the properties of the alternating group A4 in detail.
  • Learn about normal subgroups and their role in group theory.
  • Explore the concept of solvable groups and their classifications.
  • Investigate the implications of the Sylow theorems in group theory.
USEFUL FOR

Mathematicians, particularly those specializing in abstract algebra, students studying group theory, and anyone interested in the solvability of groups in relation to their order.

Homework Statement



Show that a group of order 12p is solvable for any prime p greater than 11

Homework Equations



I'm not very good about solvability questions so if anybody has any good ideas I'd be interested to hear them.

The Attempt at a Solution



I know that that every group of order 12 is either isomorphic to A4 or has an element of order 6, but I'm not really sure how to use this.

Call the group in question G. You know that G has a subgroup H of order p.

If you can show that H is a normal subgroup of G, then you know that G is solvable if and only if H and G/H are solvable. It's considerably simpler to show that H and G/H are solvable (hint: H has prime order and G/H has order 12).
