Post all questions about fields, rings, group theory, vector spaces, and the axioms that define them into this category.

Because there's sparking in DC motors, they are inherently less efficient than say AC motors are,

In general retail values for low grade coins are $7.50-$7.75, better grade are $8.00-$14.00 and coins showing almost no wear run from $40.00-$65.00.

How do you find proper subgroups of a cyclic group of order 6?

A cyclic group of order 6 is isomorphic to that generated by elements a and b where a2 = 1, b3 = 1, or to the group generated by c where c6 = 1.

So, find the identity element, 1.

Next find an element which when operated on by itself, equals the identity. This element will correspond to a or c3.

Finally find an element which when operated on by itself twice (so that it is cubed or multiplied by 3), equals the identity. This element will correspond to b or c2.

The subgroups {1}, (1, a} = {1, c3} and {1, b, b2} = {1, c2, c4} will be proper subgroups.
