Peloton Peloton In a road bicycle race, the peloton (from French, originally meaning 'platoon') is the main group or pack of riders. Riders in a group save energy by riding close (drafting or slipstreaming) near (particularly behind) other riders. The reduction in drag is dramatic; in the middle of a well-developed group drag can be reduced to as little as 5%-10%. Exploitation of this potential energy saving leads to very complex cooperative and competitive interactions between riders and teams in race tactics. The term is also used to refer to the community of professional cyclists in general, as in 'the professional
Word (group theory) Word (group theory) In group theory, a word is any written product of group elements and their inverses. For example, if "x", "y" and "z" are elements of a group "G", then "xy", "z""xzz" and "y""zxx""yz" are words in the set {"x", "y", "z"}. Two different words may evaluate to the same value in "G", or even in every group. Words play an important role in the theory of free groups and presentations, and are central objects of study in combinatorial group theory. Let "G" be a group, and let "S" be a subset of "G". A word in "S"
