Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 5 generators on 28 points:

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