Presentation

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

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

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