Talk:Janko group J4

Conjugates in relations
The relations listed for this group look wrong - the exponents should be integers only, c^b  does not make sense in a group.

 * c^b is a standard shorthand for b^-1cb, the conjugate of c by b. It reduces the lengths of the relations considerably. JackSchmidt (talk) 19:39, 22 September 2011 (UTC)
