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) "G". The word problem is one of three algorithmic problems for groups proposed by Max Dehn in 1911. It was shown by Pyotr Novikov in 1955 that there exists a finitely presented group "G" such that the word problem for "G" is undecidable. 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
