Definition talk:Center (Abstract Algebra)/Group

Examples

For the dihedral group of 2*n elements the center is $1 , r^{n/2}$ for n even and the trivial subgroup for n odd

Yep, that's a worthwhile result ... now just needs to be proved. The way this site works is that it would have its own separate page. --prime mover 06:18, 19 November 2010 (UTC)

Notation
