(Countably) infinite group generated by finite subgroups.

Post by doryphorus » Mon Oct 19, 2015 11:38 am

Could someone please give me an example of an infinite group generated by two finite subgroups? (I think you know the question I'm referring to, if a subgroup H has order 12 and K has order 30 what could be the order of the subgroup generated by H and K.)

Take the free product of the cyclic group of order 12 with the cyclic group of order 30.
