Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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