Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(2,3)(5,6,10,12,8,7,9,11)(13,14,18,20,16,21,17,22)(15,23,26,27,25,19,24,28);(1,2,4,3)(6,7)(11,12)(13,15,17,24,16,25,18,26)(14,19,22,27,21,23,20,28);(5,7,8,6)(9,11,10,12)(14,20)(15,24)(17,18)(21,22)(25,26)(27,28);(1,3,4,2)(15,25)(19,23)(24,26)(27,28)
